[MBZ] More AC fun
While waiting for parts for the evapectomy on The White Whale, I decided to tackle the compressor re-seal on the '95 E300. Getting it off the car was pretty easy, no drama. Took it apart twice - forgot to re-install the clip ring holding the shaft seal in place. Realized I didn't know the torque for the case bolts so I had to watch the u-tub vids, and then discovered that the case actually has a third big o-ring in the middle, so now I'm going to be taking it apart a third time. Fun fun! The manifold on top of the compressor doesn't want to come off, those bolts are very tight. I guess I need to put the compressor in my vice so I can get enough leverage to get that off and replace the manifold seal underneath. My o-ring kits don't have the two large o-rings for the other end of the manifold, where the suction and discharge pipes attach to the manifold. Going to dig around in all the other o-rings I've accumulated over the years, maybe I've got the right set in there somewhere, else I'll have to source them locally I guess. Also need to source a new drier.

So the AC quit working on that POS ML I got from OK Don. The compressor is kicking on so I thought maybe it was a tad low. I hooked it up to the AC machine, had a charge, compressor was running but high and low side is equilized, so I guess compressor is shot and not doing anything?

In about to set this 95 e300 on fire. All tests point to bad pbu, yet I would think if by my figuring you jump pin 7 and 13 on the left harness in the car compressor should kick on, it doesn't. I get about .6 volts at those connection as same as I get at the pressure switch. If I put positive at pin 13 which goes to fuse 7 and run a wire wire direct to ground I get 12v. If ground plug in the pressure switch on the Klima side of the switch compressor kicks on. If I have the switch hooked up and ground pin 7 in the car with a wire running direct to ground compressor kicks on. I have tested continuity between all wires the one from pin 7 in car to pressure switch, it's fine, from other side of pressure switch to pin 10 on Klima it's fine, from pin 1 on Klima to ground it's fine. That seems to be all the legs of the circuit right? Maybe I need to test from pin 13 to fuse 7 in the fuse box? Seems with positive of meter on pin 13 and neg to ground and I get 12v that would indicate that wir e is fine too, right? What piece of the puzzle am I not getting. If all these wires seems to be fine then why won't compressor kick on if pin 13 at pbu harness which comes from fuse 7 is jumped to pin 7 which goes out to the pressur switch then on to the Klima why won't that kick on the compressor? Maybe my limited electrical ability is confusing me? Or is there more to the pbu kicking on the compressor that that? Would the wires seem to test fine but still be bad or shorted or something?

All tests point to bad pbu, yet I would think if by my figuring you jump pin 7 and 13 on the left harness in the car compressor should kick on, it doesn't. I get about .6 volts at those connection as same as I get at the pressure switch. If I put positive at pin 13 which goes to fuse 7 and run a wire wire direct to ground I get 12v. If ground plug in the pressure switch on the Klima side of the switch compressor kicks on. If I have the switch hooked up and ground pin 7 in the car with a wire running direct to ground compressor kicks on. I have tested continuity between all wires the one from pin 7 in car to pressure switch, it's fine, from other side of pressure switch to pin 10 on Klima it's fine, from pin 1 on Klima to ground it's fine. That seems to be all the legs of the circuit right? Maybe I need to test from pin 13 to fuse 7 in the fuse box? Seems with positive of meter on pin 13 and neg to ground and I get 12v that would indicate that wire is fine too, right? What piece of the puzzle am I not getting. If all these wires seems to be fine then why won't compressor kick on if pin 13 at pbu harness which comes from fuse 7 is jumped to pin 7 which goes out to the pressur switch then on to the Klima why won't that kick on the compressor? Maybe my limited electrical ability is confusing me? Or is there more to the pbu kicking on the compressor that that? Would the wires seem to test fine but still be bad or shorted or something?

That would be the correct reading if the PBU is using a transistor as a switch. If ground plug in the pressure switch on the Klima side of the switch compressor kicks on. Ah! That says the KLIMA is the hold-out, since bypassing it makes the compressor turn on. Does the PBU connect to the KLIMA directly? Maybe I need to test from pin 13 to fuse 7 in the fuse box? Seems with positive of meter on pin 13 and neg to ground and I get 12v that would indicate that wire is fine too, right? With ordinary electric - yes. But a transistor switch in the PBU could have a little bit of current leak through that would show up on a meter - but not be enough to actually _do_ anything.

Re: [MBZ] More AC woes
leak but who knows, maybe that's all it is. I tried my tire core tool It doesn't take much to leak it all away. on it to see if I could tigten it but it would not fit around the barrel of the valve. Odd. Mine doesn't go around the barrel, it goes down inside and over the pin. Works fine on tires and AC valves. Cheap thing, too. Hemostats work, too. I've had several valves that were loose and that's all the significant leak there was. The vibration and heat cycling works them loose with time. I assume that the valve cores are not interchangable with a tire valve core, right? No, they're not exactly the same. Very similar. I think NAPA carries them.

[MBZ] More AC woes
To add to the chorus of AC problems -- I've been working on getting the AC going again on my 300D. It has not worked in some time and when it threw the AC belt last year summer I did not bother replacing it. With the intention to resurrect the system, I bought some servicing equiptment from Harbor Freight (vacuum pump and manifold gauge set). Last week I put a new belt on and attached the gauges. No pressure on the high side and minimal residual pressure on the low side. I vacuumed the system for half an hour. Closing the valves, it appeared to be holding. I charged the system and got some cooling. Pressures looked good but never got really cold vent temps (I got maybe into the 50s). I did notice that a lot of the cool air was being diverted to the defrost vents because water started condensing on the windshield. I did not really use the AC much on the road because the cooling was so marginal it was more comfortable to just have the windows open. Today I put the gauges back on and there was virtually no pressure in the system. So I've got a major leak somewhere, as the entire charge was lost in about 5 days, without even having had the AC on much in that time. What's the best way to isolate the leak or identify the source?

Re: [MBZ] More AC woes
With the intention to resurrect the system, I bought some servicing equipment from Harbor Freight (vacuum pump and manifold gauge set). So far, so good. I vacuumed the system for half an hour. Closing the valves, it appeared to be holding. Yep. I charged the system and got some cooling. Pressures looked good but never got really cold vent temps (I got maybe into the 50s). I did notice that a lot of the cool air was being diverted to the defrost vents because water started condensing on the windshield. Effectiveness will suck if the defrost vents don't close. You need to deal with that. Vent temps on a 123 can get down to 39 degrees on a long freeway. That's what I get with the test refrigerant, anyway.

[MBZ] More AC questions
My brother in law came over and charged the AC in my 115 76 300D yesterday afternoon. We put 134 in and it is blowing cold air. At speed it is blowing down to about 52 degrees out the centre vent so that is not bad. However, I have a couple of issues to deal with. The auxiliary fan is not running at all. The circuit seems to be fairly simple based on the schematic from the CD manual. Reading other posts on here leads me to believe that I should short the terminals on the switch that is screwed into the side of the receiver dryer doodad. The manual appears to suggest that the switch should be removed first. I don't recall anyone saying that on the list. I assume I can just use a wire as a jumper and join the terminals on the switch to see if the fan then cuts in and if so, the switch is bad - right? There are 2 small boxes above the receiver dryer that have 2 fuses in each. Are these related to the AC? I cleaned the terminals and put new fuses in but that didn't change anything. Didn't try the voltmeter to see if there is anything there. Second issue, is that I am getting air out of the driver's side vent and the centre vent but nothing from the passenger side vent. I recall something on that subject recently for newer model cars. Anyone out there know what I should be looking for on a 115?? Randy B
Re: [MBZ] More AC questions
The auxiliary fan is not running at all. You know it's only supposed to come on when the AC system gets 'too hot', right? It may be normal that it not come on for you, except sometimes. My 114 didn't have any switch on the AC system, since Yorks don't need a low-pressure safety switch and early cars didn't couple the auxiliary fan to the AC system. I added a later high-temperature switch to my drier, and cobbled it into the existing aux fan wiring. It required a diode, as I recall, to isolate the existing aux fan relay from other circuitry. (The car's overtemperature switch kicks on the fan and changes the engine timing, and I only wanted the fan to come on.) I am getting air out of the driver's side vent and the centre vent but nothing from the passenger side vent. Is the shutoff lever working? Look down the eyeball to see if it's opening up. You may also have a duct hose disconnected underneath the dash. There's nothing else there that could cause what you describe. -- Jim
Re: [MBZ] More AC questions
I think it should be coming on. We were running the car in the garage and watching the temperature of the engine and of the cold air out of the vent. At one point the compressor was trying to lock up and it stalled the car when I tried to back out of the garage. My mechanic brother in law (he is a licenced mechanic with a fair amount of AC experience but no experience on old MB's) thinks that the fan should come on and help cool the AC. It seems to be fine when the car is moving and has air flowing through the rad. The vent lever was working before we had the AC working. Lever shuts off flow of vent. Now however, with the AC on there is no airflow from the vent. Will try to take another look at it this evening.
