Hi all--

My check engine light went on today and I pulled the following codes--I looked some up in the Haynes manual but am looking for any other advice that you can offer.

A2 1-2-1 Mass Air Flow--I have had this one before and successfully cleared it (I thought) following the Bay 13 instructions
A6 4-1-1 Haynes shows Throttle Position Sensor problem
A7 1-2-2 Haynes show Temp Signal

B1 1-3-5 Haynes shows No signal from coolent sensor
4-1-7 Haynes shows Passenger side interior temp inlet fan seized

B2 1-2-2 I can't find anything on this one
B-5 2-1-1 I can't find anything on this one

Any advice would be appreciated--and if you know the approx. cost to fix that would be great. I have a pretty good indie mechanic that I have used before so I would be more than likely taking it to them.

Background on the car--it's a 93 850GLT with sunroof--176,000 miles, Auto transmission. I've previously had the PNP switch done, the rear main oil seal replaced, fuel pump replaced and i'm the timing belt done twice. I think I need a new serpentine belt soon too.

Thanks

Bill
