Check the pigtail to the resistor and the pigtail connector to the blower motor.Look for burnt wires or melted connection. The blower motor itself may be bad. You can try wiggling the connectors to see if it comes on or tapping on the blower motor.If it comes on doing either the connection is most likely very poor and needs repaired. You can also check fuses just to make sure when whatever burned out it did not blow the fuse.

If the heater core is leaking, you would get a lot of steam that would smell "sweet". That would also leave you low on coolant, which could be a source of your overheating. If it's more of an electrical smell, you may have a blower motor or a blower motor resistor going bad, but won't cause the engine to overheat.

I assume you replaced the resistor. Often, the resistor failure is caused by the switch, and replacing the resistor will result in burning up another resistor. Recommend you look at your new resistor and if it's burning up, replace the switch. Let me know if you need any instructions.

For an explanation, please see my tip at http://www.fixya.com/cars/r6234839-doesn_t_heater_or_air_conditioner_blow . These are generic instructions.

You may want to change the blower motor as a precaution.
Do all the fan speeds work?
If not .....change the fan resistor board which is right beside the fan at the same time you change the blower fan motor.

Smoke coming out of vents


if it smells like sweet antifreeze, it is
the heater core is not he A/C evaporator core.

the core fails due to not replacing the antifreeze coolant before it goes acidic ... (not doing service here)

are you getting leakage under the dash near heater box, blower area?

Antifreeze smell and smoke coming out of vents


You have a coolant leak most likely in the heater core. Try disconnecting your heater hoses and coupling them together, then running the engine to see if the leak goes away. If it does, I would have the heater core replaced.

Bad smell coming from heater/ smoke coming out vents


I had the same problem in my 98 Dodge Dakota! Replaced the heater core, problem solved. No more funky coolant smell and erie fog coming through my vents. I bought the heater core at rockauto.com online. Have purchased many items now from them. All factory parts so far at half the price of even AutoZone, even with the shipping. Also, you usually have to wait only a couple of days depending on the part and they have EVERYTHING.

1st, the fuse location is marked, what is the 20 Amp fuse for? 2nd, did the smoke have a nauseating sweet smell to it? If it smells like described it is the heater core leaking, coolant steam looks like smoke.
