[Redman0629]

I’m new to the forum so hopefully I’m posting in the right place and not breaking any rules, the problem I’m having is when I turn on my blower in any series of way a/c, heat, recirculating or not there is what smells like a burning smell maybe electrical I have no clue what’s going on, there is no other issues no noises anywhere nothing getting hot or leaking truck has 50k on it and runs like new so let me know if anyone else has had this issue or knows the fix, you you in advance.

Have you replaced your cabin air filter lately? If so maybe something fell down into the box. Does the fan blow air at an expected speed, or is it less than anticipated?
