I had all the a/c components (compressor, accumulator, condensor, hoses, orifice tube and all a/c related parts) a week ago. It blew cold air for a while but stopped blowing cold air today. I've run out of ideas please help. It's starting to get hot here in Las Vegas.

It could be your low pressure cycle switch is going bad. Check the connection to the switch and it's is located on the A/C Accumulator. The other thing to check is the A/C relay and that is located in the glove box. There is a panel in the glove box that say's relay, there is three relays in there and one of the out side relay's out of the three is the A/C. can not remember which one it is. The middle relay is the fuel pump and the other one is the third break light. Switch the two out side relays and see if your A/C get's better. the other thing too is if the R134a is just a little low, and needs to be topped off. Good luck and hope this helps. if your going to try to recharge the A/C system your self, keep in mind not to over charge.

50psi on the low side is a little high. Sounds like the system is overcharged by about 10-15psi. Overcharging a system will cause a lack of performance just as much as undercharging with one exception, overcharging can damage the compressor. The compressor will engage with as little as 20psi although there's no 1 benchmark for all engines, 40-45psi is considered a full charge. Hope this answers your question.
