Luther White Posted June 20, 2005 Report Share Posted June 20, 2005 Ok, I have searched and can't seem to find a definitive answer for this problem...maybe there is not one! But let me paint the picture and see if someone can help me, please! Ok here goes...I had a heater hose (top one) blow a couple of weeks ago, not having a lot of cash on hand right now (full-time student) I bypassed the heater core. Ok no bid deal since its summer. But since then my blower will come on for a brief moment and then turn off. Sometimes the little lights will come on and flash and the blower will not do anything, weird huh?? I read on here where some people have taken the blower moter out to inspect. So I did so, the motor seems to be fine. Turns ok! All connection seemed to be ok too. I read the codes B1 which were 414 & 418. 413-no vovltage to driver side interior sensor inlet fan & 418- no control signal to blower fan power stage. Can someone help decifer this for me and lead me in a formidable direction. 1994 850 Turbo 135,000 milesThanks, Link to comment Share on other sites More sharing options...

Luther White Posted June 21, 2005 Author Report Share Posted June 21, 2005 Thanks for the quick reply! So you think that it is the ballast resistor pack? Do you know where I can find one..part number?..and is it expensive? I thought about calling the dealer this evening but I know they are over priced...Continued guidance would be appreciated.Thanks, Link to comment Share on other sites More sharing options...
