If you still had the drier unit on there that got left open to environment the second time around then change it too and be done with it. Also this time suck it down for 2 hours if you can. To get every last bit of moisture out of there. And one other thing don't forget to address the oil needs.
Thanks for the advice. I actually shopped around online and purchased the accumulator, orifice, and both high and low side switches all AC-Delco for under 60 bucks shipped. There all sitting in my back seat.....
Two hours? Really? I have to make arrangements that he can/will do it for that long.
As far as the oil goes, I spoke to some guy at tech choice. Very helpfull, spent a ton of time with me on the phone. He said all the oil does is lubricate the compressor. I always thought it helped in removing or preventing excess mositure? He also stated if the compressor is not making noise that there is enough oil. I have no clue, just telling ya what he said.
On a side note, I added two cans oil "oil charge" yesterday. It was 2ozs of oil with 1oz of 134 per can. Only 10 bucks but should have saved my money being there gonna open the system again.
