Glad it was so cheap. and it is always nice to hear how it turned out, so often we never hear back and don't know if we were any help.

1st don't comment on a post, use the reply box below it. If you comment, it doesn't show as a new post on the thread, so unless I look back I will not...

1st check the evaporator temp with something, your vent temp may be in the 40's but the evaporator temp may be close to freezing. Air bypassing the evaporator,...

Sounds like you are having trouble getting the 134a to flow into the system, either your quick connect isn't connecting properly or someone left the...

Doubt it, the compressor is cycling, and the high side is above what static pressure would be for the temp. What do you mean by "low side maxed out'?...

[Cornbinder89]

There are a lot of things to look at, but since you paid someone to recharge and check, I would take it back to them and tell them they need to diagnose...

Sounds like your on the right track, Got to get air over the condenser.

One more thing to keep in mind, You will not see vent temps drop right away. It takes my trucks almost 30 mins to reach the vent temps you'd expect to...

[Cornbinder89]

Oh, and I don't think you have an obstruction, with those, the high side goes high and stays but the low side goes really low, often below atmospheric...

Misting shows when you get the heat out the pressures drop to more where I'd expect them to be.
My be it is just the picture but the condenser seams...

With no airflow over the condenser it is shutting down from over pressure. Do you know the fan is bad, or is it a relay or circuit breaker? you need to...

250 psi is 147 deg condensing temp or almost 60 deg over ambient! See how hot the outlet of the condenser is compared to the inlet. How good is the air...

[Cornbinder89]

You need a different gauge! A/C systems can reach pressures near 400 psi.
I agree with Chris, it does not look like an expansion valve issue. We...
