My compressor went out last summer and when I bought the new one it was for a 134 system, so I went ahead and replaced the reciever dryer and the expansion valve and recharged it and it worked great. Someone helped me recharge and I didn't think to look at the gauges for 134, and now that I'm doing it again I'm kinda just winging it.
It's not to bad fight now but for some reason my middle vents arn't working. The air is coming out the defrost vents and the side vents. Ever heard of anything like that?
