My 2007 jeep compass a/c motor comes but does not blow cold air?

If compressor isn't kicking in, check the connector atop the a/c accumulator, beside the coolant recover tank, in the engine compartment. That connector is atop a black bottle, and the connector goes to the low pressure switch. These switches do fail, and you can jump a wire across the connector terminals to see if the compressor comes on (engine running). As this circuit provides part of the ground path from the compressor clutch, if the switch is open, the compressor will never turn on. If the switch is failed, it can be replaced without opening the a/c system. Just disconnect the connector, unscrew the switch, replace it, and reconnect the connector.

Sounds like you may have a partially plugged heater core. You could flush this out separately, from flushing radiator & engine block. Diconnect heater hoses going to your heater core and clamp off, so not to loose coolant from engine. Now hook up separate hose to one side of heater core pipe and flush out with typical garden hose. Repeat procedure on both heater core inlets. Reconnect original heater hoses and test difference. You may have to add an additional litre of antifreeze. If this don't work i suggest changing heater core. Good luck.........Ron.

I agree, these vehicles have a problem with the blend doors and since the accuators hit the door when it opens and closes, it breaks the doors. and it's a huge job to replace them.

SOURCE: Jeep AC blows cold air at defrost and feet but not through vents

There is a flap that directs the air. the flap is controlled by a vacuum actuator. This is located inside the venting. The actuator is connected to little vacuum hoses that attach to the temperature control switch. Either the flap is stuck, or the actuator has gone bad.

the electric motor that open the heat door looses electrical connection there by the door stays on cold / it is located under the a/c heater assembly / which requires removing the whole dash and heater assy// also bleed all air out of coolant system
there are three doors / 1/ a/c heat 2/ mode /defors 3/ recurculation [email protected]
