420sel blower

My blower stopped suddenly with no prior noises or problems. I checked fuse #5 and the blower motor. Is my problem the climit control unit or should I check something else?

Pull the panel under the dash and then the black panel up there. the blower motor can then be checked by using a meter and checking for voltage at the regulator and the motor.

I checked the voltage and there wasn't any. If it is the control unit, where is the best deal? I've tried the PartsShop, but can"t get a response.

On 99.9% of 420SELs the blower fuse is external strip 30A style. Look just in front of fuse box, it's powered directly from ignition switch (circuit 15X).

The fuse is good and I line checked OK. I also checked the voltage in the line.
