Joined yesterday and am back with my first of many questions. I've got a 2005 passat TDI and the ac take about 5 to 10 minutes to start cooling. Once it is going its blowing nice cold air. Does anyone have any pointers where to start looking for the problem. Bit of a double whammy because 2 of the windows are inoperative at the moment (read the thread and think I can solve that problem) but until I do it's very hot here in South FL. Thanks in advance for any advice offered.

Are the AC electric fans in the front working? Bad compressor? Have the system pressure checked at a professional shop. I don't know much about AC, just trying to help and point you in the general direction. I've heard of bad relays on these cars, it's relay 384 under the dash.

Problem solved.

Update, found out about relay 384 and found a post about repairing it with a little bit of solder. Once I knew what to do it was easy. Got to the relay from behind the fuse box cover (mind you don't cut your hand on the sharp edges) pulled it out. I pried it apart with a small screwdriver to reveal the circuit board. A quick close look exposed the cracked terminal so I dumped a seagull dropping of solder, put it all back together, started the car and there was cold air blowing in my face.

I took a couple of photo's of the circuit board, just can't figure out how to get them on here yet.

Just fixed the 384 relay and saved myself at least $50 (I had to drop $10 on a soldering iron and solder).

My soldering job looked like a 1st grader's playdough sculpture, but it seems to have worked - the ac came on right away.

Hot weather seems to have triggered the complete break, so parking in the hot Texas sun tomorrow will be the true test.
