Hello, I just inherited a '97 sahara (i named it Beavis). The HVAC fan wasnt working, so during the trouble shooting, i managed to connect the battery in reverse. the system did not like this one bit. The next time i tried to start Beavis, it wouldnt start unless i was giving it gas. It would then start no problem, and as soon as i took my foot off the gas it would stall immediately. I suspect an electrical problem somewhere but not sure where, as i checked all the fuses. If anyone has an idea of why this is happening it would be greatly appreciated, as i no longer can move the vehicle.
On a smaller note, i am getting 0.8V at the blower motor terminals with fan switch on hi and 0v on all other speeds. i suspect a faulty blower resistor, but that doesnt explain the hi speed voltage. any suggestions.
