Question about Dodge Ram 1500
Out of no where it runs wide open, replaced the resister, relay and dash controll unit. even if you unplug the dash controll it runs.
Sounds like something is grounding the high speed relay.

The blower motor control module needs to be replaced, that will solve the problem. The module is underneath the hood on the firewall in the back. It has 2- 6mm screws. Unplug it, pull it out, put the other one back in. Plug it in. This is common for this model buick.

SOURCE: blower fan
Sounds like the problem is more with the blower motor assembly itself. The blower motor have micro-proccers built itnto them which comunicate with the control heads and do the actual regulating of the fan motor. Dealers have computers with diagnostic software which allows them to monitor what is happening in the eletronic controls of the vehicle. Electronic diagnostics without the diagnostic software makes it very diffecult to pinpoint the actual item causing the problem.

SOURCE: blower motor resistor
The blower motor resistor is located near the blower motor. It is held in place by 2 screws, and has a wire clip connected to it. Very simple fix.
I hope this helps you, and I wish you luck on your repair.

The blower motor control module is under the dash on the inside of the passenger side. I'm not sure what you mean by the AC Blower.... the blower contols levels and on and off. The air won't work at all if this goes.. I had it replaced on mine and had an on/off switch put in while the part came in and it cost me 217 bucks. Hope this helps.
