blower resistor blown again

Recommended Posts

I have an e36 with analogue heater and the blower resistor went a few months ago so I only had heat on power 4. I bought a new one a month ago and it worked but since a few days ago the heater is again only working on power 4. Just wondering before I go asking for a refund is there anything else I should check first?

Thanks

Current draw of the fan motor

I don't follow, what would cause that? More importantly any idea what would fix it?

Check the current draw of the fan motor. Burnt/partially motor. Get a sparky to check

the bearings could be tight causing more drag which will draw more current .

remove the fan cowling cover and see if spins freely or tight etc. also worn brushes in the motor

Oh interesting, mines done this so I can only assume the same thing is occurring. I better investigate before I replace the resistor pack, they aren't cheap!
