Well nunsa, the rebuild option is sounding better and better since I am on a very tight budget right now. Although I wont throw out the idea that something else is leaking. Might have to test it again. I'm just going on what I was told when the system was tested last. Plus I want to go ahead and covert to 134a b/c of the cost of the R12 now days. I know it doesn't cool as well but I only have a single cab and not one of those 'cavernous' 4runners <img src="/forums/images/graemlins/wink.gif" alt="" /> Anyway thanks for all the opinions and advice you guys! <img src="/forums/images/graemlins/kewl.gif" alt="" /> <img src="/forums/images/graemlins/cheers.gif" alt="" />
