Why is my pressure to high on the low side.70psi with on freon

if you put in to much freon low side will be high -same if not enough freon -if pressure taking while idling will be high and if repair was done moisture could have gotten into lines and will have to vacuum system if system is short cycling [compressor going on and off ]and at 70 # add more freon slowly and bring up the rpm on vehicle a little about 1000 rpm

I have a 1999 grandprix my Ac is blowing hot air I tried charging it and its reading over charged

Could be the compressor is not running.
When the compressor is running you have about 30psi on the low side and 250psi on the high side. When the compressor is off, both sides are equal at 70psi or so.

Craftsman air compressor model 191.135131 wont build pressure

I can not find a Craftsman compressor with that model number anywhere so here are a couple things to look into. If the compressor fills to 70psi and keeps on running check the valve plate and piston/cylinder assemblies. Check that the valve reeds on the valve plate are not bent, broken or warped from heat. Then check that the wiper (oil less) or pistion rings (oil splash) are not damaged and that the cylinder wall is not scarred up. Any of these will let the compressor fill up to the point where the air pressure leaks past the valves or piston and won't fill any further. If the compressor fills to 70psi then shuts off the problem is in the pressure switch. Some have an adjustment screw or bolt to control when it turns on and shuts off. If you had a drop from 100 to 70 the springs may be weak or broke and you'll have to replace the switch.

After moving across the country, the compressor never shuts off when plugged in. there is a hissing under the switch at a pin hole below the pressure switch. Also once the compressor reaches 70-70psi. the...

The pinhole leak is most likely your problem. However pressure switch leaks are often misdiagnosed.

Drain all the air from your tank.

Follow the 1/4" copper or plastic line that connects to the pressure switch back to where it meets a fitting that screws into the tank.

Take the lines off of that fitting and take the fitting out of the tank. That is your check valve. Be sure that isn't leaking or obstructed in anyway.

If it isn't leaking or obstructed I think you need to replace your pressure switch. Without having hands on access to your unit I can't be sure.

My ingersoll rand garagemate's regulated pressure drops from 90psi to 70psi almost instantly after using air tools, even though tank pressure is above 100psi. What is going on here? I replaced the...

are you talking about the little regulator gauge droping while you use it, as it does.its all to do with how much psi can pass through the airline at once. ther for since air is leaving the regulator it drops but when u stop using it it should shoot up straight away, if it doesnt means your regulator needs ajusted.

Many craftsman compressor are built by champbell hausfeld using a dry type of cylinder and piston (no oil, no crankcase). If dry type, check for worn cylinder and piston ring. Pieces of the vinyl ring can jamb between the reed valves in the head causing air to escape from the intake. If your compressor has a crankcase and oil, check for broken reed valves in head. Spray soap solution on hoses, checkvalve, drainvalve, and fittings to check for leaks. Most likely problem is reed valves broken or open. Parts are available from sears or match parts to enjoy

1989 year would indicate the system uses the Old CFC R12 refrigerant. 70 PSI equals about 70°F . This is not enough pressure difference to give you any cooling. Sounds like your compressor has bad valves. Replace compressor.
