HELP, I Live in the south and I have to AIR....

[epwman]

I have a 1994 E420. The blower motor went bad, common, then the regulator, common, I fixed both. The system was working fine. My acutators are bad so I didnt have air except on the side vents and the defrost vents. So I forced the center vents to open and poped off the control arm to have center air/heat at all times. Then the blower quit, came on again and quit again then stopped completely. I thought it was the regulator again so I replaced it, no luck. I put power directly to the blower and it works fine. There seems to be no power coming to the regulator from inside the car. I put a voltage tester to the regulator, the yellow wire has power the red does not.

HELP>>>> I live in the south, it is 97 degrees and humid, I work in a business suit I have to have air.
