93 Suburban Heater Control Dash Panel

Fixed my heater, 2 weeks later my dash control unit died. I bought another one that works and still nothing. I have power to the connector. I checked all fuses, is there a relay somewhere to check/replace? It has no power at all.

Any fuses that you checked, did you use a testlite on the fuse circuit to check for voltage? Even if the fuse is good, if no voltage, the circuit is still dead. Are you saying there is no voltage at the blower motor connector? My info shows a blower relay, under the dash, center. Sorry I don't have a picture.

I checked if there was voltage to the 25 amp fuse. There was. I checked the fuse which was good, but replaced it anyway. There are 2 hot wires for the control panel plug, one on each end. both have 12V power. No lights, indicators, nothing on the LCD, it's dead, but like I said, i replaced the control panel with a known good one and still nothing. I saw a picture of where the relay is mounted, That will be my next step, and thanks for your reply!
