Keffer inc Posted May 25, 2017 Share Posted May 25, 2017 Hey guys, I opened the dash where the controls are and checked that plug and I have no power going to the fan controller? I know where the fuses are under the cb, but no idea which one to look at. Anyone know? Also checked power at the fan, dead there too for what are now obvious reasons.

Keffer inc Posted May 26, 2017 Author Share Posted May 26, 2017 Well, I hit the blower with a hammer and it works now? Maybe I didn't have a good ground on my tester. Guess in time that means I need a new blower.

If your hammer don't fix it, you need a bigger hammer.Sent from my XT1254 using Tapatalk Quote Link to comment https://www.bigmacktrucks.com/topic/49970-2011-cxu613-ac-heater-blower-is-not-working/#findComment-370800 Share on other sites More sharing options...
Eastcoastdiesel Posted May 26, 2017 Share Posted May 26, 2017 Those blower are always so fickle. Before you replace your blower, check the plug before it. The 2007 cxn613's I take care of are notorious for frying them.

Rockwell Posted June 20, 2017 Share Posted June 20, 2017 I had to replace mine, still worked but was crazy loud. Not a bad job at all, I was able to replace while waiting to unload.
