Miracle in a can damage?

clueless on Sat September 26, 2009 3:15 PM User is offline

Year: 97
Make: Chevy
Model: S10
Engine Size: 2.2
Refrigerant Type: 134
Pressure Low: 70
Pressure High: 50
Country of Origin: United States

Friend bought a beater truck for misc jobs. AC doesnt work Compressor turns ok. tried to vac and charge it low side is way high high side is way low. Doesn't blow cold. Shrader valve is leaking likely the original problem. I assume someone put a miracle in a can in this and plugged it up.

Whats the odds the condenser will need to be replaced?

Thanks.

Then it will take a minor miracle to get it right.

This vehicle uses a V5 compressor which are known for control valve failures. A control valve failure would have the type of pressures you mention.

Remove the refrigerant and take out the orifice tube and check it for sealer or debris. If sealer is present, a total system replacement may be necessary.

My opinion, if a sealer had plugged this system on the high side you would see a very high side pressure. If a sealer had plugged the low side you would see the system pull into a vacuum. Pulling the OT is fine but if you really want to check for sealer that hardens remove the accumulator and cut it in half. I personaly think with the data provided it's low on refrigerant with a stuck CV. But that's why we go thought the diagnostic procedures!

Why can't one simple aspect of a AC diagnostic procedure be understood. The system must be fully charge, properly with a known amount of refrigerant not just pressures, before a true diagnostic procedure can be completed.
If this 'sealer' is a non hardening product (more than likely) and not a 'hardening' product, then the problem may not be a 'total system' failure.
The control valve could be the problem...but one must have know that the system if properly/fully charged prior to making a determination.
Recover,evac and recharge the system....test....then post results.....help will arrive very soon.

Tag said 28 OZ put 24 in it. Close enough to get the info you need? There are other problems in the electrical system that need to be worked out compressor has to be jumped to make it work.

This is just a beater and the guy that owns is not likely going to but a bunch of $$$ in it so I am trying to decide if this is worth messing with on a budget.

Thanks for the help.
