Question about AC Cars & Trucks
Posted by Anonymous on
You could have something caught in the interior air fan, it could be loose or broken, or it could have a bad bearing. Without knowing make, model and year, can't tell you much else to look at.

SOURCE: Clicking noise coming from under
You have a blend door motor that bad. The clicking noise is probably the motor turing and grinding the gears...Prob should take too a shop for a diag to be sure...Some of them things are pretty hard to get to

Concerning your broken vent -- this can be caused by a broken linkage or a malfunctioning servo motor as well. these vent have air ducts the sway back and forth to adjust the dual air flow function. if the servo o linkages are malfunctioning or not connected for some reason, it will not allow total control of the air flow and temperature range. Now, if you have a combination of a flow error and temperature error as well, thai can be caused by a combination of the two.
In this case, you will need to inspect the linkages as well as the servo motor function as well. in addition, i would test the air temp sensors for there operational value. they control the temp when you adjust the coll or hot function.
Concerning the Loud noise coming from the blower fan---
This issue can be caused by a misalignment within the blower housing or, it can also be caused by some minor damage within the motor itself, causing it to rotate in a erratic manner, in return, forcing it to rub against the housing itself. the best solution here is to extract this blower fan housing and inspect for lose fan propeller and motor stability. replace parts accordingly.
PLease rate and have a great day:)

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?

SOURCE: Heater Blower won't work
Find the blower motor on the passenger side just above where the passengers feet would be. You may need to remove a panel (fairly easy). You will see a round metal housing about 4" in diameter. Turn on the ignition key and blower motor. Then tap the housing with a small hammer or a screwdriver. If the blower comes on.....replace the motor. If not, find the wires leading to that motor, undo the connector and check for power and ground in them.(You did check fuses first...right?)
