1988 F-150 Airways
 

What's up everyone, question related to my truck's airways. So my defroster works great, but when i switch to panel, lower, or mix, it still just blows out the defroster vent. Any ideas on what I should check? Does this truck still utilize cables or does it have vacuum lines? Thanks!

It does still utilize cables however I am told it also has vacuum lines.
Curious what your fix will be as my 88 does the same thing.

Thanks for that! Btw, love your truck pics, thats a bad ass looking rig!!

Thanks. Let us know what the problem was when you get it fixed.

Will do, might be a little while, gotta wait for a warmer day where I'm not fishing haha!

Is the fix an easy one? My 89 F250 does the same thing
