My heater and AC dont pump out much air, i think they are clogged. My friends T/A really blows air at ya but mine is really week. Any ideas ?

 

Does it blow out of all the vents at once or does air constantly come out of the defrost vents?? I would start be checked the check valve and then the lines for cracks/ leaks.

 

The same thing happened with my old car. Does it blow harder on one side then the other? If so, your hose is clogged or leaking. Mine ended up being disconnected completly. Check the simple stuff first and then move on the the harder(expensive) stuff. Good luck.
