" From what you're saying, even if that hot lead off of the horn relay is not hooked up, the blower should still work on the lower speeds, right? Right now it is not hooked up."
From what I believe that is correct. I was out looking at my elky a bit ago and it appears that the wire from the fuse holder goes into the wire bundle/connector at the heater box resistor & then joins with the wire going to the motor. IF this is a correct ASSUMPTION, with the key ON and the blower switch in any run position (except HI) AND the hot lead disconnected at the horn relay you should read the voltage that is coming from the switch & thru the resistors and then to the motor when you put a meter on the wire which is disconnected from the horn relay. This should check the entire circuit from the interior fuse panel, thru the switch & then thru the resistor. With the blower speed set to Lo you will have a few volts (guessing 6-8), on Med the voltage should rise a bit (8-10???) . Thes are just guestimates but the important thing is that you have some voltage at Lo and slightly more at medium. AND - did you remove the entire fender??? What does it take to do that on the streets of NYC??? On Nov 24, 2007 4:52 PM, John Nasta <[EMAIL PROTECTED]> wrote: > Thanks Rick, > > That color diagram is super-nice.
