Here I am almost a year later and still no A/C shame on me! I finally had it last week when it was way too hot for me. I had stopped trouble shooting because I didn't have a way to test the duty cycle on the G65 sensor. So this morning, I just picked one up and put it on the car and crossed my fingers... but still nothing
As I continued through the pdf, this is where I got a little more confused. Step 5 through the end, does the car have to be running still or just in ignition on, a/c on and fan on first setting?
So here is where I am at tonight, car is cold, but car is running, radiator fans on low with A/C on and cabin fan on first setting, no clutch engagement. I disconnected the plug to the compressor and measured voltage. I read 4.18V... then it would double to a lil over 8 and go back to 4.18V, but never made it to 9.5V.
Question 1: do I still need to measure with load or is it safe to say, there is just not enough voltage to turn compressor clutch on? After checking the voltage, I shut the car off and even at my lowest setting, unplugged, measuring compressor side, I get 1 for the resistance, you stated 4 ohms, so is mine broken lol?
Question 2: should this be done with car on? I don't think it matters because we are measuring resistance using multimeter, right?
Steps 6 through the end I checked with the car not running disconnected the harness for T14, then put key in ignition, AC button on and fan on 1st setting,
Question 3: is this correct or should the car be running this whole time?
T14-8, had a little less than 12V, 11.75
T14-9, had 12V
T14-4, had 12V
T14-6, had trouble reading resistance, maybe because of my ground, but eventually got .5 ohm
T14-14 and T14-5, i had beep for continuity
T14-2, here we go again with the duty cycle... I can't measure, do I need a new multimeter
T14-3 is where I stopped... it's getting late and I need to get some sleep, but part of the reason, is I was starting to not understand at this point. When I check for the pulsing voltage, what should it be... or am I just looking for on/off to see if FCM is not allowing it to turn on? More duty cycle talk
then you mention "
throttle basic settings" what is this and why would I lose what was orignally there?
Last thing you mention is that I can provide voltage on pin 1 while grounding pin 2 to test a/c clutch, this is on the compressor plug correct?
Dan, thanks in advance for the help and patience with all of us. If I can't figure this out in the next few days, I may just have to bite the bullet and take to dealer
