ever since i had blower motor changed for front heat i get a burning odor when the heat is turned on . does anyone know a possible cause for this.

 

Loose ground or pinched hot wire causing sparking and melting plastic?

 

Yeah, you should be able to visually see something if that's the case... Might have to dig in there and look around - did you replace the blower motor or the shop? If it's the shop, I'd take it back and let them know.

If you did, well you know the answer to that. I don't suspect it's anything real 'normal' however.

Although - there's one small possibility too - there's a relay in there for the fan speed that's known to be a 'problem child' part. Are you aware of that one? Potentially a new motor could bring more current through it and cause it to fail since there's been a recent change?

Dunno - that's a real long shot. You know how it goes sometimes, when you replace one part that's bad, it functioning right can sometimes put more strain on other parts..

And FYI - my connector was simply melted too - I had to get the 'kit' for that - to replace the connector.

Long short, but it's worth peeking under the dash. On the 2003 Durango at least, it's right under the glove box on the passenger side. Easy to get to.

 

What kind of "burning" smell is it? Burning oil? Burning plastic? Burning paper? They all have different smells when they burn.

Knowing that could really help pin it down.

 

Indeed.. good point
