This is way complicated involving taking out dashboard and heating unit. Will cost about $700 to have someone do it. You can do it yourself if you have some mechanical knowledge. But not over a fixya. Buy a chiltons manual at auto part store and look up to see how hard it is.

The problem is the Blower Motor Resistor Pack is defective. Purchase the Pack so you will know what you are looking for. It can be located in a few locations. It can be behind the glove box, behind the kick panel on the passenger side, or next to the blower motor. I am almost certain yours is located behind the glove box but not 100% sure. Hope this helps you.

Testimonial: "clay58 good job on the resistor. Right on info. "
Plan on finding a melted blower motor resistor. Usually when the blower goes single speed, the blower motor resistor is the cause.
You can find it on the passenger side, looking up behind the dash / Glove box area.
In this picture the passenger side kick panel ( where the inertia fuel switch is at ) is on the right hand side of the picture.
This is what it might look like when you get it out :
The blower motor only has the 1 fuse and blower motor relay on it. If it works on high, those are OK..
Parts should be less than 75.00 total from a dealer, and it is a metric socket and lay on your back on the passenger side floor repair, real easy and quick.

I just started experiencing the same problem. Yes, typically after rainy days, I can never get the interior lights to go out after the ignition key has been removed. The car acts as if there is a door open. Now, my latest problem is with the heater fan. Of course, putting the control in the "off" position will turn it off but you can turn it on and off with no ignition key installed. I'm also having problems with my heater core too so it's been a pain in the but!!
I believe this problem has also caused my battery to die which is why I'm on this site in the first place!! I can't get into the car with the keys and the dead battery won't allow me to unlock the car!! When it rains it pours!!!
