Well after driving the car with the air on for a few days, now it's back to not working right. It sounds like the compressor is kicking on, but the air is blowing hot, and I mean HOT. It is to the point of almost burning my hand if I leave it in front of the vent. I had gotten the a/c charged right ...

I had the exact same problem with the solder joints. Once I got everything soldered I tested it several times in the car and everything worked perfectly. So I got to work on putting everything back together. Once everything was buttoned up I started it up and started to pull away from the house, hit ...

if you need some pictures let me know, I have that extra one that I can take apart again

Well I took it all apart and added solder to every spot on that connection, hooked it up and YAHTZEE!! It was getting dark, so tomorrow I am looking forward to putting the dash back together. Thanks again to the great write up. I was so happy it worked that I took apart the second unit that I had ...

Thank you for the great explanation, I will have a chance to get back in and try this process a little later in the day. Souds like it will work to me though.

I just had the system charged a few weeks back hoping that was my problem so I am pretty sure it rules that out.

So you think that since I can apply pressure upward on the yellow connector that the problem is a bad solder joint on that immediate board? Does that board come out cleanly? Do I just ...

Do you have any other suggestions as to what could be wrong?

I see more VW products on the side of the road (and frequently, and relatively new) than any other company (yes, even more than old Chrysler products or Korean makes).

Sure you may see more newer VW on the side of the road, but keep in mind that all car manufactures have done away with the ...

Well I figured I should post an update to see if anyone knows whats happening.

I pulled the controls out of the dash and put in a new(used) one to see if that was the problem. With the new one in I noticed that if you bumped or wiggled the wiring harness that plugs into the back yellow plug; you ...

bump

OK? I pulled the relays and checked while the unit was selected to Max A/C and then also with it switched to Off. Both times the relay ports had power. Now the other weird part, to me maybe it makes sense to someone else, I pulled the fuse for the A/C in the same compartment and tested for power ...

Thank you, I will try testing the fuse box, and then probably take the controller out of the dash and put in another used one to see if that solves anything

Does anybody think that it could be the contols on the inside not sending the voltage, our do you think a wire is cut somewhere?

I've searched many of the archives but can't find any a/c electrical issues covering this. I am hoping to get some kind of diagram or chart depicting how the electricity ...

I guess I should have specified that this is on a 90' legacy L wagon w/manual

I am having problem with my a/c and am hoping that someone can offer some helpful suggestions. Whats happening is this: Obviously the a/c is not working when selected by the a/c button inside. The fan blows warm air and the compressor doesn't kick on. Now, if you unplug the harness on top of the ...
