97 ZJ 5.2 with manual temp controls
Right after Thanksgiving, I went out to start the ZJ and the battery was dead. I charged that battery and the next morning, drove the ZJ to church. When I came out, the battery was dead again. Took that battery home, charged it and put it back in. Only this time, I noticed that the blower motor was running with the ZJ off. I did a search on NACGA and found that the blower resistor can short out to ground causing the blower motor to run all the time. I put in a new blower motor resistor and all was well....for two weeks.
This morning, when I got back in the ZJ after stopping at the donut shop, I noticed that the blower motor was running on its own again. I just reached down and unplugged the blower motor resistor and it shut off. I'm hesitant to believe that the resistor has failed again. I'm leaning towards something else causing with a path to ground that is causing the issue. Has anyone had a similar problem? Any ideas on what else to check? Could the blower motor itself be the issue?
