I have an '03 KR 5.4L, and recently had some a/c issues, some that I fixed. I FIXED the EATC O-rings, so described in these forums, and I have A/C. In doing that, I tested vacuum, and now the vents work well, though not blowing fully--but I will take what I can get.

The only remaining issue is the blower, which I straight wired to get power to it. What do I need to check/replace to get the fan working again through the variable switch of the EATC? Fuses are ok. Resitor, reostat? (I did see the passion displayed earlier).

Thank you in advance.
