Fan blower control

[Mobie1]

Hi my 1995 sidekick js..
the blower switch has lost it's first 3 settings, I've been running on # 4 for about 4 years now #5 still works also..any quick fix to re-enable the lower settings?..Thanks

I once had the same problem. The contacts that the selector slides across get dirty and quit working. Cleaning them shoulfd fix it, I can't remember how I cleaned mine, if I needed to remove the cover or not, maybe you can get a rag and screw driver in there.

okay i removed the face place..pulled off the tabs on control sliders..then removed face plate I shot some contact cleaner in the gap..so far no Joy.

What I use for contact cleaner; WD-40. Works well but you have to spray it, move the lever back/forth a few times to clean and LET DRY for about 30 minutes before sending any current through, I've melted switches because of wet WD-40.
