Re: Not blowing cold air after charging

System may be freezing up. Does the air flow out of the vents diminish? What are the before and after pressures? Lots of info has been left out. Does the clutch still operate? Does your compressor have a control valve in it?

Re: R134a price up over 500%

The EPA was planning to abolish r134a. A recent court ruling has decided to stop this from happening. Same thing for r410, R404. Thank you President Trump.

Re: 73 stingray with high AC pressure

The above is exactly correct. Spray a water hose on your condenser. If all pressures drop, you have proven what was said. Use R12 and be done with it.

Re: 1975 Corvette AC Recharge

You can access the low side just about anywhere. Be advised, R134a in Corvettes has not been the best choice of refrigerant.

Re: Thanks for the add and RV2 questions

If the circuit is the same as a 69 Dart, there is a temperature control switch. It is in the circuit right before the low pressure switch.
