just last week my AC compressor in the coupe stopped working. after checking it out, it turns out the issue was at the AC compressor relay. see that relay has 4 wires that look like this...
magnet side:
#2 blk/yel- this is the power source from the inner fuse box
#1 red/blu- this is the ground controlled by the TCU/ECU
switched side:
#3 red- this goes to the AC compressor clutch
#4 blk/yel- this is the power source from the inner fuse box (spliced with #2)
...now all of the wires work right except #1. it is suppose to act as a ECU controlled ground. but its pushing out 12 volts. so the AC compressor clutch never activates. has anyone ever had this issue? Im wondering if its a bad computer.
for now Ive grounded the #1 wire. so that every time I turn the car on, the AC compressor clutch activates. whether or not the AC blower is on.
btw anyone using a haynes manual, its got the wire numbers for this relay incorrect. I had to write the right ones on the book
