I am having a problem with the heater blower. Replaced blower motor.(old one did not run) Now after checking circuits, switch, grounds, etc. it will run then shut off. If I replace the fuse, it will run and shut off ( fuse tests ok). I have replaced the rheostat in the heater box to no avail. Any suggestions? THANKS EVERETT

 

Found the problem with the blower motor. It eventually lead to other electrical "glitches." The whole problem stemmed from a corroded fuse block, connections, fuse terminals,etc. Replaced fuse block. Everything seems normal now. Just thought I would pass this on FYI.

 

glad ya found it. many thanks for getting back and letting us know
