A/C not cold Sign In

Year of vehicle: 1992
Make of vehicle: Ford
Model of vehicle: Explorer
Engine size: 4.0L
Mileage/Kilometers: 130,000

This '92 Ford Explorer was converted to R134a two years ago when the compressor failed. To make a long story short, the mechanic did a piss-poor job that cost me big $$$ and wouldn't make good on it. The system would not hold refrigerant after that and several cans of refrigerant were used up in short order.

The car has sat unused for the last two years until last month I decided to try to fix it up for my girlfriend to use. I located and fixed the refrigerant leak, and the system holds either vacuum or pressure. I evacuated the system and put in about 18 ounces of R134a. I would have added a little more but the system wouldn't take any more in.

The vent temperature only gets down to 80f on a hot West Texas day. The low side pressure is a fairly constant 40psi and the compressor is engaged all the time at idle.

What's happening here? Is it likely that this problem is the result of an excessive amount of oil in the system from adding too many cans? If so, what do I do?

I welcome your ideas.

Did you vacuum the system down before recharging it?
Is the accumulator getting cold?
What is the high pressure reading?
What prevented you from putting more refrigerant in?
