1994 pickup blower motor

I have 1994 4x4 pickup. The blower motor stopped abruptly while running the A/C. the motor stopped and the a/c is out. The fuses under the glove box are all good and I replaced the relay. If I jump the terminals in the relay plug everything works fine including the fan switch. I am not getting power to the activation part of the relay. Am I missing a fuse somewhere? Where does that power source come from?

Sounds like either the control panel or the A/C amplifier burned out

Just how did you jump the relay that is the question??

Get the correct relay ?? Did you test prior to installing??

You have voltage to the coil and you have voltage on one side of the contacts

If you jumped the contacts it will turn on the blower motor

The 40 amp fuse is most often on the right side near the Circuit Opening Relay if that was open doubtful the 10 amp gauge fuse that powers the coil side would start the blower motor

Turns out that the power for the relay comes off fuse marked gauges. Problem solved!

Had power to the switch part of the relay but not to the terminal that activates the relay.
