    A/C Issues...

    Ok. I have a problem. I am not getting cold ai when my a/c is on. I jsut get air blown at me..when it is cooler out, I get cooler air, but when it is hot out, i jsut get hot air..It REALLY sucks, cause it's REALLY humid here..MN is either hot or cold..never just right. So, What can I do? I don't have much money at all, and I got a trip cummin up in 2 weeks, that I need this taken care of. It has a dye in the system, to check for leaks..I have a blacklight..will that work? I think all the system needs is a recharge, but I have no idea..even if it did, can I do this myself? I really gotta get this fixed...

    AC is not really a DIY kinda thing unless you wanna spent alot of time on it. What I would recommend you do is take the car to a dedicated AC shop. Look in the yellow pages under ac, you will see that there are places that specialize in AC work for all aplications. I had a leak in my car last year , and took it to a AC place. They put a UV die in the system, found and fixed the leak , and recharged it for like 80 bucks. I took it to a meachanic before that and he said he could recharge it with R12 for $200 but it would all just leak out again or he could "make a project out of it', and convert it to R134 for like $500 . I later found out at the AC place that the new R134 is a much shittier refrigerant then R12 and it's more prone to leaks.

      find a shop that deals with a/c recharging. i had my a/c recharged and retrofitted to r134 for about $130..they also did a compression/leakdown test too.

        Ya I had the same problem. I couldnt handle it so I had a guy do mine for me that I know personally. He did it for 150 plus 10 bucks for the knob that controls the temp. He totally hooked me up.

          A true R134 conversion would be about that much because of the labor that's involved. Officially you need to change every seal in the system and get a compressor that's compatible with R134. Then you'd also need to change the orifice tube.

          Now, in reality, you can usually get away with just evacuating the system, using R134 oil and charging up with '134.

            yea thats all i did. got a r134 kit from kragens and a friend at the shop changed the fittings and flushed the system for free. now if i need a recharge i can buy a can at any autoshop for about $5

              evacuating R12

              i had to get R134a to recharge my ac. this is the first time i had to do this since i owned the car. so i have to check to see if there is R12 in the system or if its R134a. how do i check to see if it is R12 and if so, can i evacuate it (how)?

                well, usually there is a sticker along a fender somewhere, telling you of the fluid in the car, and when dye was last placed in the system..I wanna see if I can detect a leak myself..how can I do this? also, is it really taht easy..just remove the r12, and replace wit r134?

                  Its the easy way to do it but in reality there's suppose to be more to it. If you take the time to change the orifice tube near the evaporator you'll get much better results. Basically, that tube controls the pressure in the system. The R134 one will be higher pressure then the R12 one so the performance should be very similar.

                  I still don't see how you can do AC work without a vacuum pump...
