Hello and thanks for using JustAnswer.I will try my best to help you with your question.
Is the air blowing out the defroster vents on top of the dash or out the floor ducts under the dash?
Customer: replied 2 years ago.
Neither. The fan seems to not be blowing at all in the front. I have tried running the fan speed up and down. nothing. The rear seems to be running fine.
Expert:  A. Penland replied 2 years ago.
The blower fan is located under the dash on the passenger side below the glove box. You will need to check for power and ground to the blower motor when the AC is on. You should have power on the YELLOW?GREEN striped wire and ground on the YELLOW/BLUE striped wire. If you have power and ground, replace the blower motor. If you have power but no ground, you will have to replace the Blower Speed Controller which is mounted right next to the blower motor.

power, no ground. Will be getting blower Speed Controller and replacing it. I will let you know then. Would that have been what caused the burning electrical smell?
Expert:  A. Penland replied 2 years ago.
Please keep me informed.

old speed controller was the cause of the smell. New part will be here friday at the earliest.
