Kevin3 0 Report post Posted July 9, 2013 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 Quote Share this post Link to post Share on other sites

Kevin3 0 Report post Posted July 9, 2013 I don't follow, what would cause that? More importantly any idea what would fix it? Quote Share this post Link to post Share on other sites
hotwire 352 Report post Posted July 9, 2013 Check the current draw of the fan motor. Burnt/partially motor. Get a sparky to check Quote Share this post Link to post Share on other sites
BM WORLD 1258 Report post Posted July 9, 2013 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 Quote Share this post Link to post Share on other sites

Michael. 2312 Report post Posted July 10, 2013 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! Quote Share this post Link to post Share on other sites
