Re: [MBZ] AC Question W124 91 300D re Evap Repl.

Reading the manual for the SD I find that changing the system to max cool and high fan will cut out fresh air to the cabin. Normal mix seems to be 60/40 using auto fan clay > On Jul 22, 2017, at 4:25 AM, Mitch Haley via Mercedes > wrote: > > >> On July 22, 2017 at

That doesn't sound right. On both my '87 and my '95, the Recirc button works in Auto, Economy. The system will draw in outside air at all times unless the Recirc button is pushed, and then it has a timer so after 45 minutes or so it starts drawing outside air again. - Max Charleston

Yep, my 124 has a Recirc Button, the only way to introduce outside air to to push the far right button which turns off the AC and turns the Outside Air On. Then it's temp is controlled with the Temp roller. I know some have criticized the ACC but I have followed the OM advice and left it in

Re: [MBZ] AC Question W124 91 300D re Evap Repl.

Mitch is correct, Larry is wrong - the re-circulation button must be engaged manually on a 124. However, if the system was working before and now the performance is degraded, that may no solve the problem. - Max Charleston SC On Sat, Jul 22, 2017 at 7:25 AM, Mitch Haley via Mercedes

Re: [MBZ] AC Question W124 91 300D re Evap Repl.

Thanks Guys - re Outside Air - this is a W124 with ACC so all that stuff is done automatically. But I'll make sure that servo is working properly. My wife drove is some yesterday and reported cold air again. LarryT On 07/21/2017 10:19 PM, archer75--- via Mercedes wrote: If your car has an

Re: [MBZ] AC Question W124 91 300D re Evap Repl.

If your car has an outside air/inside air setting, be sure it's not set on outside air. Cool air at night doesn't affect the inside temp as much as outside air in the heat of the day. Also,you might get a $50-60 set of gauges from HF or elsewhere and follow instructions. FLAPS has books on auto

Re: [MBZ] AC Question W124 91 300D re Evap Repl.

Very hard to tell from what you mention. Is the aux fan running? That will make a big difference. Could be a little low also. Sent from my iPhone > On Jul 21, 2017, at 5:28 PM, Larry Turner via Mercedes > wrote: > > Hi Gang, > Some may remember back in 2014 when I R'd

[MBZ] AC Question W124 91 300D re Evap Repl.

Hi Gang, Some may remember back in 2014 when I R'd my AC Evaporator (had to do it twice when I found I had a DOA Evap) to fix a leak. It worked great until this year when it was no longer cooling the cabin properly. The odd (IMO) symptom is it worked great on cloudy days, when the humidity
