Thread: Replaced blower motor and got a loud POP from dash....

Does the blower work on all settings?

If the blower resistors melted the fan may only work on high and there may be an electrical burning smell associated with this.

If some dust came out of the vents when you first turned it then a critter may have taken up residence in your plumbing. The pop you heard may have just been some debris going through the fan.

The fan spins pretty fast and it may have disintegrated whatever debris went through it.

Go buy a fire extinguisher and keep it on the floor for few days, just in case. LOL

it could have been a door in the hvac set up getting full blast air from the fan and slamming a door shut, up over the glove box the is a door that opens and closes, when i opened that area up so i could see it, it makes a good shutting noise, the smoke could have been dust or dirt, if it had no smell to it, like burnt electrical wires or such.

not 100% sure but the rec button may close that door to keep fresh air from coming in the car. and usually you feel the air blowing a bit harder when the a/c is on recirculate.

Yea, it guess it could have been a blend door dislodging after sitting for three years.

yeah it drops like a guillotine, up and down. CHOP!

If it were a large cap then it would have filled the interior with really bad odor. Ask me how I know.

either your short on refrigerant or the blend door actuator on the drive side.

you filled it up? or a shop? if you did you use a real gauge?

if its low the driver side can blow warm. fill it up, see what happens,

i would clean all the connections, pipes, everything and wipe them all down, and when the a/c stops working again look for the leak. most of the time there will be a oily residue left from the refrigerant leaking out at the leaky connection.

or sensor. they have a O ring they sit on that leaks sometimes, a 1/4 turn or less tighter can sometime stop that from leaking.
