I have electronic speed control fan adjustments. It had 4 settings, low-high. Problem is only the low and high adjustment buttons work. Is there a relay switch or fuse that can be replaced to fix the problem? Any ideas as to why it's not working and what can be done to fix it yourself without having to take it to a dealership or mechanic shop? I'm fairly mechanically inclined but like I said I do not know what's causing the two fan speed adjustments in the middle to not work.

Thanks
Suthrn; you make me laugh. I did not know you were mechanically inclined. Where is this blow motor relay located? I'd imagine the engine compartment, but where?

Yes, you have what is called a 'blower motor relay'. Most parts supply houses should carry those.

Dodge man is correct. I meant to say resister. Like he says, easy to get to and takes a few minutes to change. Just follow his directions. Sorry about that. I'm in the office and should be concentrating on my paperwork. :)
