I am having problems with my A/C. When the A/C works, it works great. However, it just quits working frequently, (usually when it is 95 degrees outside). I have had the freon checked by VW dealer as I suspected either a low or high pressure switch was the problem. They said everything checks out, (of course the A/C was working when I stopped by). I just installed a new fan control module which is a pain to install as the battery box had to come completely out. Did not help as the problem still exists. I have checked the fuses and wiring on top of the battery and everything checks out ok with my meter. Any ideas from anyone???
