OK, my blower motor will not work on any of the speed settings. It worked last week. Here is what i'v checked and come up with:

It's not getting power at the motor connectorit IS getting power at both blower motor fusesit Is getting power at the 1 relay i found for it ( i don't have any manuals or diagrams)The motor itself ohmed around 3 ohms, seems kinda low, but it's not burned up

So all i can think of now is that the HVAC controller in the dash is screwed up, but i don't really know how to check it out with out some diagrams or someting.

Is there a common problem with this? Or can some one help me look further into this? I just need help because it's getting cooler and no heater this winter will suck. Thanks in advance for any help!

did you check the resistor pack?

there's a resistor pack somewhere next to the blower I think, it has a fuseable link in it according to the FMS

follow wires: colors are blue-white, -red, -yellow, and -black

Here's a thought,

why don't you just run energize the blower motor and it if works then you know to look else where.
