Pontiac Repair: 91 pontiac sunbird, pontiac sunbird, engine control module


Question
is there a fuse for the fan. the fan was replaced but it is still not kicking in and i'm still overheating

Answer
Hi Debbie:

Yes there is a fuse for the fan But it may not be the fuse. it could be a bad fan relay,coolant tempature sensor or engine control module. A scan tool needs to be hooked up to this car and see #1 what the coolant tempature is showing and then when it gets hot enough if the engine control module is trying to turn the fan on or not. It could even be a bad connection or bad ground to the fan motor. Good luck :)
