My 93 buick heater fan won't quit running after car is off. Any ideas what it is and where it's found?:shield:

Try checking out if the heater fan relay and/or the fan switch is sticking, on my '84 century it has a 3 position "switch".. on/off, low and high speeds...it would get dirty contacts same for the relay

:confused: :clonk:

You probably will need to replace your blower control module ,it is under your hood at the center area of the firewall ..three 7mm screws hold it in place ( you can unplug it to turn the blower motor off until you get the $ for the part ) HTH
