I have a new module but havnt put it in, problem is fan doesn’t go full speed and jumps around, untill today I noticed the fan just will not turn off ever. I’m hoping this module is the fix.
Before you install anything, I would recommend that you clean your drains under the windshield cowl. They're probably clogged and the water flows in the passenger side by the blower motor.
There are a few videos on you tube that show how to do this or you can search the forum.
