Ok...if it's not one thing, it's another...now my lines coming from the R12 cylinder unit right by the downpipe are forming ALOT of water and sometimes even ice around the them. When I turn the car off...the ice melts quickly to water and starts dripping all over...a pretty big puddle of water forms right behind the front pass tire. What the heck is causing this? It never did this before. I had my R12 unit recharged this summer.

Does the comperssor cycle, or is on all the time. Sound kinda like the system is overcharged.
May be the low pressure switch on the accumlator thats stuck
Must be nice to be in a climate wear you still need A/C.

My GN's been in storage for a month already and even though it's been a unseasnoably warm fall and there's no snow yet the heaters are going strong.
Good thing my Monte Carlo had a V8 and a great heater. -40'C, no problem just pump it twice and turn the key, ignoring all the funcky noises that come from an engine that starts that cold.

Well the thing is...I have not used my AC in months...I've been using my heater as well (new heater core put in). It just recently started doing this after I changed my downpipe (which shouldn't make a difference I thought!). It's the weirdest thing I have seen...so how exactly do you get the accumulator switch unstuck if it is? I know nothing about how the a/c works in these cars...

They often do that when a bit low on freon and the compressor is cycling...very common when recharging a system or when it has lost a bit-obviously prevalent on humid days....very common to sweat but low freon will cause it to form ice...

you know this car is WEIRD...

first I had the boost problems...then I had this water problem with the a/c lines...

i tried EVERYTHING i could think of for the boost problems...then it finally dawned on me to maybe try switching back to the stock chip...well guess what???

the frickin boost is back and the lines didn't have one single drop of condensation on them! ummmmmmmmm ok so switching just my chip killed two birds with one stone i guess...WEIRD is all i gotta say

The defroster circuit runs the A/C compressor.

Bet you've been using that, right?
