Thanks for visiting Just Answer,
Is it just the blowe fan that is inoperative?
Customer: replied 4 years ago.
But Both Of The Fan Are Up And Running On The Car
Expert:  Tim West replied 4 years ago.
The fans in the front of the radiator are working you mean?
Customer: replied 4 years ago.
yes that is what i mean
Expert:  Tim West replied 4 years ago.
Thanks, XXXXX XXXXX fans at the radiator are different than the fan for the blower motor. So even though those fans work, the blower could still be out.
Saying that, let's fix the blower motor.
Check the Gray or Gray/Black wire and see if changing the blower speeds will affect the voltage on that circuit. Ground the Brown wire at the blower motor and see if the motor will run. If the motor is getting power and will not run, replace the blower motor.
The blower is behind the glove box.
If it needs to be replaced,

Let me know. The coolant hoses are the 2 hoses that go into the firewall. Passenger side, under the hood.
Customer: replied 4 years ago.

okay so what do i do after that

 

Expert:  Tim West replied 4 years ago.
Depends if they are warm. If they aren't warm at all, check the coolant level and replace the thermostat.
If one is warm, flush the heater core and the cooling system.
If both are warm, you might have a temperature door broken.
Let me know.
Customer: replied 4 years ago.

okay one other thing i did a Toneup on my car and i want the check Engine light off
Expert:  Tim West replied 4 years ago.
That's no problem. If you need the engine light off you can do 2 things, remove the battery. Or go to Autozone and have them use a scan tool to do it. They should do it free. Just tell them you want it scanned. Was the light on before you did a tune up?
Customer: replied 4 years ago.
no it was not
Expert:  Tim West replied 4 years ago.
OKay, just to be safe take it to Autozone and have them read the code and clear it.
Make sure there isn't anything wrong. (probably not) If you don't want to drive. Just remove the battery a few minutes.
