After a recent trip up to the San Francisco Bay Area, I noticed a "ticking"
noise which came from the passenger side. The sound increased when I turned
up the heater so I knew it was related to the operation of the heater
and the AC unit.
Though this repair job was performed to correct the ticking sound, it
might not be bad idea to clean this unit especially if you have allergies.
The amount of caked on dust was pretty eye-opening. And this maintenance
item will only take an hour of your time.
Step 1: Removing the Glove Box
To remove the glove box, unscrew the two philips head screws. Lift out
the glove both to remove. Then, use a 10mm socket to remove the bottom
support bar. You may want to remove the bottom kick panel for some more
2: Removing the Fan Unit
Space is tight and you might need to do some Olympic gymnast moves to
remove this, but its do-able. Take your cordless drill with the #25 torx
bit and unscrew the three torx bits. The fan unit should just simply fall
you can see why its necessary to use a flexible shaft on your drill
torx bits (T)
remove the fan unit, unplug the black harness attached to it. It took
awhile for me to get that one off.
3: Cleaning the Unit
It was clears
as day that there were twigs and leaves that had blown in there. It was
simple to remove them. But as you can see, the amount of caked on dirt
on the fan blades was pretty disgusting. The best way to hold the unit
upside down over your sink to avoid any water getting into the fan unit
itself. Then clean the fan unit with a brush dipped in mild, soapy water.
