Weird burning smell nearest passenger side front end grill / radiator. I can place my nose over that area with H3 turned on/off and I can smell a burning plastic smell.
It's not anti freeze as my nose knows that smell very well. There is no anti freeze leaks. I have dye in the system from when i replaced it and I'd be able to see that pretty easy.
Also,the radiator was replaced a few thousand miles ago. It also is not oil as my jeep Cherokee xj has that stank continuously lol:thumbs::giggle:
It started during this cold spell the Midwest has been having approximately 5 days ago (it's been 0 to -7 below at night). I let the H3 warm up for about 10-15 minutes and when I go to drive the first couple seconds there is this weird burning smell in the air. It will intermittently do this from time to time while driving. Other times I smell nothing all day.
It is not from inside the cab or directly related to Hvac as far as I can tell.
Oil checks clean
Trans fluid checks clean
Brake fluid checked
Anti freeze checked
Window wash full, checked
Each of the respective fluids are clean and filled appropriately with the correct fluid. I also thought about possibly the bumper touching but there are no wires behind the outer corner of the plastic bumper. Riding lights are turned off.

You'll need to check and see if the fan turns with relative ease or if it takes quite a bit of effort. If it's difficult to turn, it's failing. I know unless you had checked before, it might be hard to tell what is "normal". If you have another H3 (or really any car with a working fan clutch), just give it a spin to know what normal is. Everyone I've ever seen is about the same. Don't take any personal offense to this, but as a cover my butt disclaimer to anyone out there who is common sense deficient, it should be noted you check this with the engine off.
