AC issues sanden 508 So guys I'm new to ls1 tech so I have a 1985 c10 with 2003 5.3 I bought the dirty dingo ac kit has the sanden 508 compressor my gauges are reading good but is not blowing cold air my accumulator is not cold but my liquid right where the orfis tube is at is cold it's like if it's spinning backwards could that be the problem that the compressor is spinning backwards? If anyone has an idea or has ran in into the same issue I would appreciate your help thanks

if the compressor was going backwards then your pressures would not be correct on the gauge.
If you using the stock c10 evaporator the fixed orifice tube may be clogged.
What are your pressures reading high and low? what is your ambient temperature?
What is the temperature of the Condenser?

according to the r134a chart, your AC pressures are way off. (Google "r134a chart")
Looks like Ike there is a restriction somewhere. Probably the orifice tube like stated before.
the condenser temp will be proportional to the amount of heat the evaporator is pulling out of the cab.

did you pull a full vacuum before charging the system?

Did you use stop leak at any time, or the 134 can mixed with stop leak? It's a known issue to clog the orifice.
Youll need to pull a full vacuum for at least 30 minutes with a hot engine bay to remove all air/moisture. The pressures you listed could also be from air in the system.
