    No cold or hot air comes out the front dash vents, only the defrost vents. All vaccum lines appear to be connected.

    My jeep seems to have several problems with it but the one I'm curious about right now is the air conditioner/ heater. Sometimes the vents blow, but usually just defrost, and vent on the passenger floor board for the rear seat works great. Is it a fuse? I looked for the vacuum leak and can't find a visible leak anywhere. Considering it's not constantly malfunctioning I'm assuming a switch or sensor?

    A/C works but only comes out of the defrost. C/C works very poorly (set at 65 dwindles down slowly)

    broken air flow piece (or piece that determines which vent the hot or cold air comes from does not open & shut. It is constant heat.

I have a 2011 Chevrolet Equinox LTZ and my question involves the heating/ AC unit. The air flow seems to be very strong through the Defroster but for the dash vents and the floor it seems to be much s


Defrost has been stronger on all types. Just the way plenums are made. Clear that wind shield first. As long as you have plenty of heat to keep the cabin area warm to hot, it's OK. I wouldn't woory about it.

Barely any heat coming from vents blower motor working


check the coolant level & condition of antifreeze make sure it is not dirty/rusty/muddy if thats ok try a new thermostat & radiator cap if the antifreeze is muddy you may have to blow out the heater core

Air conditioning and heating


have the water pump checked out, i had a van that did the same thing and founf i had a bad water pump it fixed the problem.also check the blower motor to make sure its working right by tapping on it while you have the car running. the car will survive dont worry its going to be one of those two things im pretty sure.
