Default Fan Question/Problem

Since it was raining like mad yesterday, I tried turning on my fan to blow some heat and dry off my new mats (The tri-bar pony ones from AM, love them). Problem is, it seems as if it's stuck on the first setting. Temperature can be changed, but not the fan speed does not change even when I turn the ****. I pulled off the **** to see if its stuck or anything and it looked fine.

Could this be a fuse issue? Or something else? I'm probably going to end up pulling it apart to see if the wires in the back of the **** got disconnected.

Did you try it in all four blower motor speeds? There is a blower motor resistor that regulates the air flow for the three lower speeds. In the fourth (highest) speed, the resistor is bypassed. If you just have a problem with the three lower speeds, then I would suspect something with the resistor. If the speed stays on low for all four speeds, then I would suspect a short circuit or a bad switch.

Yeah I've tried all the speeds, all the same (light, like the first speed). I'm wondering if because of the rain, and the known leak problem, some water got in there and messed something up. I'm going to have to look it over thourghly
