Hello all,

We are at end of winter, got a tad icy the other day, turned on truck to defrost the windshield.
​​​​​​ Day before was fine. This time, got into truck and blower was minimal, heat is there, just not blowing out.

Replaced blower resistor, which original was fine, no scorch, didn't get anywhere. It still starts like it's fine, then Peter's out.....blowers not that hard to change but would like to hear what others did. Fuses look good.

Thanks

 

What year vehicle? 2011 Extended cab
which AC controls?

Are you sure it's not defaulting to defrost?

 

It's the entire blower, any setting, even when pointing to feet. turns on fine at full speed or any setting, then fades out.
I can turn it off for a bit, and start it back up,. Does start fine, then fades out

 

HINT/TIP: Put your -complete- vehicle information (year, model, cab, trim, engine, wheelbase, _x4 drive, mileage, modifications, etc., etc.) in your signature -OR- provide it in your posting(s).
.

 

Again, "which AC controls?"

You MUST provide requested configuration information or we can't do much to help you.

 

I dont know what you mean? AC what? I don't know this abbreviation. Air conditioning?

Thanks
Ann

 

Do you have single or dual climate controls?
manual ***** or automatic buttons?
