I've downloaded wiring schematics and troubleshooting from here:
http://carfix.stufftoread.com/air-conditioning.html but still cannot find my problem. My AC compressor does not kick on when i hit my AC button (the button lights up but only room temp air blows from vents). My AC is fully charged and contains dye to detect leaks but none were found.
I am able to jump the compressor and get it to kick on and cold air blows from the vents while compressor is running. Both AC relays under the hood seem to be okay, I swaped the relays with one another with the same result and even put in a new relay to see if the compressor would kick on.
The pink wire on relay 4 is at 12V but the troubleshooting guide says it should be ground. When I touch a test light to the pink wire the compressor kicks on and it goes to 5V. The guide says that the AC amp is detecting a fault if there is 12V on the pink wire.
I have checked all the wires on the AC amp and they all check out. 2100 ohms on the freeze thermisor wires. All the other wires checked out also. Anything else I should be looking for?
