This is could be another good preventive maintenance that we overlooked, after your car run over 150 000km, the condenser fan is very important part for the heat exchange system to help the condenser dissipation heat efficiently from hot compressed gasses supplied by the compressor, if it failed, it may cause idle problem when you turn on the air conditioning system.
First thing is to remove the fan by remove the bolt that hold the fan (blue circle).
Unplug the fan motor socket and remove the few relay (for the space) and remove the bottom right bolt…
and the bottom left side.
I also remove the exhaust manifold heat shield for the space…
and the radiator fan too! (this is a good change to replace radiator fan motor carbon brushes). By removing 4 bolts that attached the fan to the radiator.
To remove the motor from the casing and the fan blade is a piece of cake.
Here we go.
Remove the 3 locking tabs by using chisel or flat screwdriver (not proper, but it’s work!) with hammer.
The carbon brushes seem at the dead end. Unfortunately, I did not found the perfect shape for the replacement, so, I modified from the alternator carbon brushes using file (I mean…a tools file) and small grits sand paper.
Need a patient booster…
Cut the middle of the old carbon brushes wire, and cut the new one exactly same length with the old one, soldering together, put back everything, fortunately, there is spring holder pin (red circle), important : Don’t forget to release it back after you Insert the rotor.
Polishing the commutator using small grits sand paper.
Check for the worn bearing, replace if need, mine like the new one!
Reinstall everthing, important : don’t forget to stake back the motor casing locking tab using chisel or other method, I believe it will go for another 150 000km and save your precious money from buying the new motor.
