Diagnostics Code 850

posted by  someone claiming to be Newbie on  Sat May 14 10:37 CST 2005 [RELATED]

I have a 93 Volvo 850 GLT. Recently it's service light turned on. I read about reading the diagnostic code from some sites and did a quick read on my car.
Can someone with explains the following diagnostic code?

B1 Code
2-3-4
4-1-1

I believe the REC and AC lights had been flashing for a while since the winter (according to the owner's manual it's a symptom of Climatic Control trouble, that's why I went after B1 code).

As I am new to the car, I have not purchased the Pocket Data Booklet that explains the diagnostic code. Can someone help me with this?

Thank you.

    If you go to the FAQ700 section here or Volvospeed.com, all of the codes are listed there also. Clear the codes as a matter of course, some of the ECC codes can just be anomolies(sp) and stay clear. You would know if the blower isn't working.
    The service light can also be turned off using the little black boxes.

    These codes are listed in the Haynes Manual. It would be worth it for you to buy one...commonly found now at Autozone and other auto parts stores for under $20.00. The 2-3-4 code means "Floor/defrost damper motor position sensor shorted to earth." This could mean a number of things. 4-1-1 means that your blower motor is not working..."blower fan seized or drawing excessive current." These parts are not cheap but also not excessive. The blower motor is located on the passenger side under the glovebox/kick panel area, but I would not recommend that you service this yourself unless you're used to doing somewhat difficult repairs yourself...one reason is because the airbag gas unit is in there too...so you have to be very very careful.

    I would recommend that you find a good independent mechanic that knows this car...if lucky he'll let you order the fan yourself. I've bought one from Borton a few years ago and saved a bunch of $$.
