Diagnosing this will be subject to a process of elimination. It could be the radio, blower motor or any other accessory particularly ones with moving parts; Try switching those off and try to note when this problem occurs and what is on/whatyou are doing. Something is getting hot causing the smell so it will be a situation where the accessory will have to run a while before doing it. It is a possibility that there is an electical curcuit overheating, but less likely. Lets rule out accessories first and give us an update. GL

Try having your braking system checked, it may be a vacuum problem. I had the same problem and it was a vacuum problem...it's easy to fix.

SOURCE: T/C lite stays on

This is the traction control light. Try to push the button and hold it for a few seconds and see if you get stability system disabled or something like that on your DIC...There is more information on the T/C function in your owners manual.
I hope this helps.
