The air bag light stays on & the blower in not working. I checked the fuses good. Any answers??

 

count the flashes from the air bag when you start up, look up the code. could be the connection to the seat has come disconnected. Mine is on because I took the passenger seat out and I put in a replacement seat from a 1999, just the cushions but there's no connection like on the 2001 seat cushions.

 

You mean the air conditioner blower?
i had low speeds stop working on my 2001 Ranger. Found through this forum that it was a blown resistor pack.
I bought this and fixed it.

Search the forum for installation instructions. It's a bit of a pain but not terrible.
