Actually I had to rig up some electrical tape to cover the top of it as that piece of plastic that spans across UNDER the white connector on the motor was broken, and speed 3 would stop working when the cover was installed. If this diode blows the fan will no longer work, failure is usually caused by a high draw blower motor. Delivering the highest standards in New, OEM & Rebuilt Porsche parts. High speed from the switch will still come to the speed resistor board and only go through that resistor fuse I mentioned. ) Using a multimeter set on the Ohm scale, use the positive lead and test the black wire. Bypassing or adding a relay to keep blower motor resistor connectors from burning out I have a 2004 Chevy Express van and I am on my 5th set of parts. Wifes blower quite working yesterday and am a little confused after doing some troubleshooting.
