Lost the speed control on the blower motor in an 04 TJ/LJ. Changed speed control switch swaped out the 2 relayes behind clove box ether though the wire color coding showed no tie in with blower motor, switch out HVAC relay under hood. CAN'T find a RESISTER anywhere that would control fan speed. Tried to trace back blower motor wires and look like thier headed back to drivers side. I'm LOST is the resister built into the motor? Any help would be GREATLY appreciated.

Yup, replace a few of them. Not to hard to get to. All blower resisters will be found in near the discharge of the blower itself, on the housing (needed to keep them cool).
