Question
QUESTION: Hi i just bought my 1997 jeep wrangler, the ac and the heat systems works fine (there is cold and hot air).

but the blower on speed 1 almost not blowing anything and as you increase the speed you get a little more air but much more noise it feel like it is clogged or something.

do i need to replace the blower motor? or maybe a clean up?

Thank you.
