Check fuse and relay for blower motor under hood. Then check ground on battery to body and for cleanliness on battery terminal ends.

Thanks for helping. Radio and wipers are now fixed, but blower motor still not working. I'm getting no voltage from live wire to blower motor resister with key on and switch set to high. Fuse is good and relay is good. Any advice would be much helpful. Thanks!

Hey PUFFNSTUFF,

Use a test light to see if the blower motor is getting power and a good ground, most likely the blower motor is bad, here is a guide that will help you.

Hi. Think it may be a fuse box issue. No power to resistor. Bypassed relay and everything works. Thanks for helping!

That relay is controlled by the body module, here is a wiring diagram. It could need replacement. Test for trigger at the relay and go from there,

Here is a guide to test from

Please let us know happens so it will help others.
