I would suggest you take it to a dealer as it should be covered under a new car warrantee if under 36000 miles

SOURCE: 1993 mazda 626 LX 2.0L. Smelled burning smell

Sounds like you have burned a belt off the pulley for the alternator and water pump. Dont drive the car until you have verified the belt is intact and the water pump is turning. Something had to have caused it if it did, I would suspect water pump, alternator, or air conditioning compressor has siezed if your car is equipped with it.

SOURCE: mazda 626 2002 smells like burning rubber

This is not good. Sounds like the heater fan bearing and/or resistor is burning out. Not familiar with your heater fan location, but most will be removeable from engine compartment.

Just remove it and spin it by hand or hook auxillary power to it to test. Some autoparts stores can test it for you. Stuff a rag in the opening to block fumes if this must be driven for parts run.

Burning plastic smell when cold out run heater and fan inside car and out


Are you loosing radiator fluid. sometimes the heater core will rupture and you will smell burn odor. also check for strange rubbing sounds or screeching coming from the blower fan motor. or engine exhaust manifolds are hot when car is on, make sure nothing is leaning on them which will cause a burn odor. Any odor coming from outside will find it's way inside through the fresh air vents.

Tcs and check engine lights came on while driving, then cruise control and smell of anti-freeze or oil comes thru when heater/air blowing on


Go to an auto parts store to get the code(s) read for free from the OBD. That will likely explain the Check Engine light (emissions related).

Also sounds like the screws weren't torqued enough (or Loc-tite not applied) by your repair mechanic.

Recall that radiator water (and anti-freeze) is what circulates in the heater core. Hopefully it is just a leaky core and turning off the heat (or shutting of that water circuit) will eliminate the smell.

Are you losing radiator water? That would be a tip-off.

Have you checked for water in the engine oil? Bad news if that's the problem.

Heater and aircon not working,loud rattling noise and smoke from vent,now not power to fan


It appears your fan itself burned out. When a field coil of an electrical fan burns out it usually makes a lot of smoke. The noise could be something that fell in there that stopped the fan from turning freely. I can imagine it heated up under the strain and burned out.

When you restarted it was burnt out so hence no noise and no fan.
The smell of the smoke should also be clue. Electrical field coils burning has an awful soury type of smell.

I have a 2005 chevrolet equinox the other day it started making this really loud sound like loud static coming from the speakers and the radio was off and you could smell wires burning can anyone help me


Yee gads! this issue sounds like something is shorted to ground, most anything of that type would broadcast into the radio.

Locate, immediately, the source of the burning wire smell. this issue is a serious FIRE HAZZARD. Do not let up until you find it. Burning wire smell, presuming that is what is happening, often results in major car fire... Find the burning wires and you will have your answer.

Loud noise from under the dash, ac/heater area. No cool air 97 li


If this noise is a clicking sound and is coming from the front center of the dash, then it may be the blender door motor which will require removal of the dash to replace it. It will keep the door from switching from heat to a/c. Does the odor smell like you have a freon leak in your a/c evaporator core or does it smell like a rat stuck in your heater and a/c ducts?
