I have a 2000 Grand Voyager SE. It has been a great van. The problem I'm having is that when I turn the heat on, the it only turns on with the switch set to the highest position. The other four positions do not turn the blower on at all. I'm wondering if anybody else has had this problem and if so, what you did to remedy it. Any and all help is greatly appreciated.
Thanks

Very common problem.
You need to replace the resistor behind the glove compartment

Remove the glove box (pressing in the sides to release the plastic clips)
There you see the resistor with 2 bolts > replace resistor
You can buy them cheap on E-bay

At least in my 2002 its that way

 

Thanks, I will try that first. I wasn't sure if it might be the switch itself gone bad so thank you.

 

Resistor located under the hood on my van. Pulled it out and it is shot melted the electrical connector and everything. Now I have to go to the junkyard and cut a connector off another van. How exciting. Good looks on the advice, Vmaxxer. Thank you.

 

Your welcome
But why not order it on ebay? Its a very common fault on a Chrysler and big chance you find a (near) broken one on the junkyard.
