Low air coming out of the dash vents.

[idahomoto]

I have a 2002 explorer, and when using heater or ac, I get very low air flow out the dash vents. Any ideas? Thanks

I think its the blower voltage regulator but im not sure. Are you sure the knob is turning the metal pin behind it?

Welcome to this forum! I've moved your thread to the A/C & heater section. Does it blow with full strength while it's in the defrost setting?

 

[idahomoto]

Yes it does. Checking it out, it blows out hardest from defrost then all the other vents. At each setting, it blows out defrost.

You have a cracked plastic vacuum line near a vacuum servo piston.

Thanks for the reply. After looking a little bit further, I found that the arm to the defrost is broken. Now I need to figure out how to fix that.

Could you take a picture of the damaged part?

I'll get a picture this weekend. I just had shoulder surgery,and running a little slow.

Welcome to this forum! Check for cracked plastic vacuum tubing as previously suggested.
