I have the '94 Ford Ranger w/ 134A refrigerenat. It was not putting out cold air so I added a can of 134A-- still no cold air-- no cool tubes under the hood-- compresser is cycling on and off about every 10-- 15 seconds.

What would be a next DIY step to perform???

Any general specs on that AC system???

Thanks.
 






what are the pressures in the system?

was this a retrofit or a factory R-134a system?
 






Hook up a manifold and take some readings.

The Haynes book says ('94 Ford Explorer w/factory R-134a system)........at ambient air temp of 80 degrees F, hi velocity fan in front of the condenser. Engine running at 1500 RPM........you should have, 22-50 low side and 160-250 high side pressure.

Capacities: oil 7 oz and R-134a 2.25 lbs (36 oz).

HTH.

Aloha, Mark
