The blower will not come on at all. It's hot outside here in South Carolina and I need help fast. How can I fix this.
Same symptoms as described. Replaced FSU/Blower Motor Resistor and problem seems to be solved. Made the repair myself. Part cost $67 at an import car parts store. Net savings of $183 from dealer costs (labor & parts).
heater motor under hood runs and drains battery after engine shut off.. resets of computer by battery disconnects with turn off of heater fan stops this but is very inconvenient
Blower motor worked erratically, then gave up entirely. BMW dealer mechanic said this is common for the vintage.
Fan flows at full blast. Dealer fix under warranty
blower fan speed increases and decreases eratically. went away after the internal resistor was replaced.
Fan switch works intermittently(ac/heat)
Fan motor stopped working. Replaced the final stage fan resister and everything working again.
