2002 Explorer with an A/C problem.

[b4]

I have a 2002 explorer, ac comes out of front vents only on lowest fan speed, once turned up the air comes out from the defrost vents. The air may be going else where, but sounds like its coming from the defrost. With summer coming on, need to fix asap. Any ideas?

Welcome to this forum! I've moved your thread into the A/C & heater section. It sounds like you might have a broken or disconnected vacuum line or vacuum reserve tank.
