I have a 1993 Jeep Grand Gerokee that just developed this problem today. The heater won't turn off. I turn the dial on the console to off and the heater/fan keeps running blowing air out the vents. This continues to happen even when I turn the car off and remove the keys. When the Jeep is on I can switch between my other heater options with no problem. And when i do switch from "off" to the other options I hear the fan get louder so the switch on my console doesn't seem to be completely broken.

About 3 weeks ago the Jeep began leaking anti-freeze. I took it to a shop and they replaced the water pump and it fixed the issue. Prior to that there was a loud whinning sound kinda like a belt that was rubbing on something. This only seemed to happen when the heater was on and I accelerated or made a turn. After replacing the water pump both the leaking and the noise went away. Not sure if it has anything to do with my current issue but I thought the background info would be good.

Any help would be greatly appreciated.

Thanks in advance.
