Title: AC again??
Post by: Just a Six? on May 14 2012, 10:56:34 AM: I went out & started to try the AC to see whats up. R-12 is full & you can see that the system is trying to turn on because the fans will try to start every few seconds. Then I remembered last year at BPG the AC Cycling Switch on Accumulator needed to be unplugged & hotwired to work. When we got back i put in some R-12 & it worked fine. I changed that switch about 3-4 years ago. Just now I went to look at NOS4GN for one $21 & remembered I have a new polished Accumulator & Switch I got maybe 4-5 years ago. Totally forgot I had the switch sitting on the shelf. The problem is finding a shop to remove & save my R-12 so I can swap in the Polished parts. maybe i'll start checking around?
Anyways my question is Any ideas why the switch would go bad (if it's the issue) after only 4 years??

I'm just swapping the switch for now since freon is good & jumping the terminals makes it work fine. I'm not swapping accumulator until down the road sometime.
I just can't drive a car without AC or I'll go nuts!

I had a jumper in at BPG but later on at home in the fall I tried the normal hookup & the AC worked. Maybe due to cooler weather or just a fluke?
Yesterday I jumped it again & it was fine, so today I put in my shiny new Cycling Switch & it's fine. For whatever reason that switch from 3-4 years ago died on me?
It was a GM part from Glen but for $20 each no big deal.
