1990 R1500 blower motor not running after heater core replacement
Tahoe & SuburbanThe power, space, and brutal towing ability make the Tahoe and its longer sibling, the Suburban, arguably the best full size SUV's on the market today.
1990 R1500 blower motor not running after heater core replacement
I just replaced the heater core in my friend's 1990 Suburban R1500, and now the blower doesn't run. I didn't knowingly disconnect any electrical connectors. Can anyone direct me to resources for a fuse diagram and wiring diagrams?
Also, does anyone know of any hot spots where I might have been likely to disconnect or pinch a wire during this job? If it makes a difference, it was the one where you have to remove the heater box with the 3 studs through the firewall, not the one where you pop the bottom off the heater box.
Thanks!
For anyone researching the same problem, it was super simple. I accidentally disconnected the power wire to the blower while disconnecting the heater hoses.
