Fan control issues

[Ben Geller]

It seems my fan control is acting up now.



Setting 1 - normal low fan

Setting 2 - a little more fan, but barely noticeable

Setting 3 - a little more than 2, but just barely

Setting 4 - Tons of air movement.



This is on all vent, defrost, and floor settings.



Any ideas?

The blend door acting up. check the vacuum hose on the pasenger side, under dash.



edit; or the resistor on the fan motor going bad..

Could also be the resister that is mounted on the air box. If it fails, you will get partial speed and almost always full speed.

Yeah, could be the blower motor resistor
