2003 GMC Savana Blower motor runs when van is not running

I can tell you where it is located, but, I don't believe that is the problem. The blower relay and resistor are an integrated assembly, The voltage is hot all the time or goes hot when you turn on the key. The hvac control module controls the ground for those circuits.

For the 1500 Savanna, you may have to remove the engine coolant bottle, under the hood, to get at the blower motor. The pigtail for the blower motor goes to the relay/resistor assembly. That assembly should be close to the blower motor.

I'm glad you got it fixed. My thinking was, it might be a ground problem, in that case, it might lead you back to the hvac control module. Stay warm.

I looked at a G-3500 savana. The blower motor resistors in under the hood on passenger side. If that's what your asking? You need to make your own post, less confusing. Sorry it took so long to get back.
