2002 Explorer climate fan only works on low.

[Gamer]

I just bought a 2002 V8 Explorer. The climate fan will only blow out air on low speed. When I turn it up to high it sounds like it's blowing but no air comes out. I had a similar problem with a 2001 Taurus. Replaced the blower motor resistor and it corrected the problem. Is it the same fix? If so where is it located? Is it still behind the glovebox? Thanks.

Welcome to this forum! I've moved your thread into the A/C & heater section. The resistor should be on the blower housing if you have the standard control. Electronic climate control uses a module instead of the resistor.

I have the standard control. Both the AC and heat work. It will blow out both on low through the center vents, no air thru the center vents above low speed. Therefore I don't think it's the blend door. It also blows out the rear vents and defrost at all speeds. Vaccum leak? Where would I check first?

Check the speed control resistor.

Where is that located?

I'm getting confused since you edited your post. You originally said that it only works on a low speed. Now it works on every speed, but it doesn't come out of every vent?

Air/Heat only comes out of the center vents on low speed when the knob is set to that setting. You can turn it up and it sounds like a tornado but air/heat will not blow out other than low speed. It will blow out the defrost vents on all speeds when set to defrost. It will also blow out air/heat on the rear vents at all speeds when you adjust it by the rear control. I guess what I'm trynig to say is the only problem is with the center dash vents.

It sounds like a vacuum problem. Check the hard plastic vacuum lines for cracks.
