Crazy, I hooked those 3 lines up and re-soldered the joints on the amp.
I fired the car up and tried the AC. I get different blower speeds but I have the dreaded "No center vent" blues...
Strange the way it was working, then not, and I removed/reinstalled the fuse and it started working again. Then died on it's own.
I had the ignition on and I heard the servo working with the thumb wheel. It seemed to move incrementally with the wheel which was promising!! I did notice that the amp got pretty hot. No smoke or anything, just really warm.
So I fired up the car to see if the wheel was controlling the temp but I couldn't really tell
Then I shut the car off and now I can't seem to get the AC to work without the engine running. It'll work for about a minute (The blower changes speed) but I can't hear the servo over the blower and auxilliary fan.
The engine still won't turn off with the wrong button pushed (I need to start writing it down) but I did change from one setting to another with it running and it shut off. This is a clue...
I guess I need to get a service manual to check out the WHOLE AC system.
I would REALLY like to get this system working!
I don't imagine the center vent pod is routed through the amp or servo?
Where exactly is the pod that runs the center vent and how do I test it?
Thanks
