SOURCE: 1998 gmc sonoma air conditioner - not cold

Check the magnetic clutch is engaged on front of a/c pump, have the motor running, a/c on and fan on high, if the centre hub is static the pump in not switched on, this can happen when the gas pressure gets low.

SOURCE: The A/C unit is not blowing cold air in the front.

your split manifold located on the firewall that sends and directs the refrigerant from the front and rear depending on your setting on the dash is plugged or the climate control on the dash is not responding and there could be a fuse,relay,broken wire,but there cant be a leak or either side wouldn't cool

SOURCE: front a/c blows cold air but back is blowing hot air

Could be low on freon, a faulty expansion valve on the rear system, or other issues. Can you tell if the rear ac lines are hot and cold ?

My new ac unit isnt blowing out cold enough

What's the temp been out side? If its over 95 degrees only expect you air to blow at about 75. It's an air conditioner not a cold air maker.

Car blows warm air when idling

It sounds like your AC unit could be overheating or even damaged.

AC units have a sensor that will turn them off automatically to prevent damage from overheating. If there is an insufficient amount of air flow, the unit will heat up, and then eventually turn off.

When the car is moving, more air is forced over the unit, likely keeping it cool enough to run, however, when the car come to a stop, it loses that air flow, and quickly heats up. Thus, the AC would work while the vehicle is in motion, and overheat and stop when the car is stopped and idling.

However, the AC unit could be completely blown. The cold air while moving could be just a case of air being forced into the car. Think of a house fan, the fast the wind blows on you, the cooler it gets.... Thus, it could be an illusion that the AC is working when car is in motion, when it really isn't.

Hope this helps.

Ac unit working fine,but when I turn the knb to heat,cold air

Check to make sure it is full of coolant, if it is then the motor that controls the blend door is bad or stuck.

The HVAC controls could also be the problem.
