I have a 1998 Chevrolet Astro Van and the blower quit the other day, so I thought I lost the blower, I checked voltage to the plug and it measured 13.89 volts on the high setting so I pulled the blower out and tested it by just plugging it in and it worked. I thought it was intermitten and decided to replace it, after a new blower it worked fine for a couple days and then all of a sudden it's inop, then it starts working on MED and LOW but will not work on HIGH. My question is doesn't the high setting bypass the resistor so wouldn't that rule out a bad resistor and point towards it being a bad controler?
Thanks
On my 95 Astro van, the fire wall connector (behind the battery) was making intermittent contact, so the fan would not work on H. Connector was melted due to high current over so many years into fan. Replaced connector (dealer part) and fan.

Thank you, I didn't want to buy a $285.00 dash control when it may be the resistor.
Thanks
