I got a relativelly cheap but very nice 745 '92 vagon.
But A/C stopped working about half a year later.
Mechanic said that AC controller needs to be replaced and asked $900.

I'm a computer guy, I guess I could buy a used part and replace it myself.
Just connect the wires of the same color and that's it?
Is it more to it?
Should I try?

(I did small things like oil changes, spark-plug replacements,
brake-cylinder replacements on my other old cars in the past, so I'm not a
total looser, and I know how to screw and unscrew stuff.... :)

Thanks a bunch!

You don't have to color code it. Just unplug the old one and pulg the new
one in.

Jumper 12V through a fuse dirrectly to the compressor clutch and make sure the
AC works with the controller bypassed.
Then..
My standard reply;
"Go to a 'U PICK' junk yard".
Learn how to take one out without damaging the dash.
Take it home and open it up and look for bad solder joints. (In a 94 940 the
relay to board joint cracks).
Put in the "New" controler.
If it works, great. If not, open up the one you took out and try to fix it.
