Air conditioning will not cool. I charged the system with 134a and the compressor kicks on and off and will not cool the jimmy.
Make sure the pressure is 25 to 45 psi on the low side and that the pipes are getting cold on the low side.
Could be the vacuum controlled motors inside the dash.
Set climate control to hot then cold or the temperature control lever from hot to cold and listen for the vacuum motor operating the flap inside that changes the flow from the heater core to the evaporator inside the dash area.
Good luck to you.
Sounds like your compressor is getting too hot. Does it get cold when you are moving down the road? My Jimmy did the same thing and I live in Arizona where A/C is a must have and found the fan clutch was bad. Maybe worth looking into... Good luck.
