A/C Blower Fan
Im researching on how to get more performance out of my Blower fan so I can get more vent pressure. now while investigating I found that the red wire on the blower resistor got very very hot (depicted in the picture). Is this normal or is this a sign of a relay going out? I cleaned the motor and fan and oiled the motor also and still no improvement. Is there a upgrade I seem to remember someone installing a suburban blower motor once but I cant find anything about it.

If the valves/doors are functioning correctly in the blower/ac box and distribution assembly it's a blower motor performance issue. Put 12V and a ground only to the motor. What now? Check for leaks at the evaporator housing and even trash in the evaporator fins. There is a filter on the face of the evaporator. #7 this image is a filter: Evap Housing.png Last edited by WVZR-1; 06-18-2013 at 09:26 AM. |

Re: A/C Blower Fan
Id try replacing the blower fan if its never been seen too before. I had a blower issue on mine I could bang the outside of the suitcase housing and the pitch would increase. The blower fan is a $50 and 1 hr job to fix. Keep in mind that little motor and the squirrel cage have been running for over 20 years. It might just need a refresh to return to normal performance. Also while you are there clean the quirrel cage and vacuum out the suitcase free of dirt, leaves etc. GC
