Hi all i'm new to the forum and am hoping for some pointers on an 850 blower motor !!! the car is a 1996 (850) the blower fault started intermittently sometimes running 3 months without fault !!.... now when i really need it with the cold weather its packed up completely
.
My checks so far are power to the blower motor engine running 9v ( should i be seeing 12+v ?? ) removed and ran the blower fan from a slave battery spins up fine....found the climate diagnostic method online and pulled trouble codes 325,411,414,418,419.... here's where i'm stumped..would the drivers side sensor fan seized (414) stop the blower fan running as a safety cutout?? passenger side fan (411) seized or over current... it spins freely and runs fine off the slave battery at 12v ?...also if i slide the fan speed slider should i be seeing the 9v supply to the motor dropping and rising with the slider ? would really appreciate some help from forum members as its off the road with the bad weather till i can get her fixed......Many Thanks Simon
