Ive been having growing concerns my fan is working improperly. I've seen it engage but it is not as common as I once believed. I understand the fan only activates above a certain temperature and then shuts off.
I'm not too sure if it's functioning properly.
Is there a proper test along with diagnostics that I can do that's hopefully within my skill range?
If needed ill provide documentation, as provided by alldata.com
Press both AUTO on the ACC for over 10 second and the fan should go full speed with/out engine running. I used that to bring the temp (close/above 100) down when coming home with AC on and had to stop at several stop lights, about a block from home turn the AC off and press both AUTO, radio/music off window down and I can hear the fan kicking in by the time I got home the temp was below 90, and I knew the aux fan work as it should be.
Look like it's on the way out, could be the bearing dry out or the brush near the end of its life. I would try to relub. the bearing to see how it turn out, try squirt some brake cleaner to clean the bearing and then lube with white grease. The second fan on the left turn by the belt connect to the one run by motor.
Could be the rust from the residual of the drive thru water effect.
I will take a look at the part again after work. When the bearing fails I'd expect more resistance with the fan spinning. There seems to be very little resistance but some is noticeable. It's hard to tell if it is abnormal. Will post more when I take that closer look. Thanks kman.
the connector is on the top right (when standing in front of the car) underneath the A/C connector flap. It´s then quite easy to give 12volt directly to the fan, and see if it spins up. If they don´t when you give them the boot, the Module (on the drivers side, behind the bumper..) for the fans is likely to be broken.
If the fans don´t spin up to produce quite a storm, then the motor is likely corroded, and you have to replace the whole assembly.
What you should´t neglect is the Visco Fan, if the Visco Clutch is worn, the cooling power is greatly diminished - and the E-Fans are the last line of overheating defense!
Thanks for the tip memyself, how would I give 12 volts directly to the fan? I apologize if this seems like a simple task to do. As for my viscous fan, It was fixed recently along with the clutch because my engine would reach hell like temperatures, thankfully no longer does that happen. I think the biggest problem the aux fans cause is a semi cold ac system when at an idle. It is noticeably cooler when on the road or when these fans are somewhat moving at a standstill. When they are not moving it can get uncomfortable if it is a really hot day. So please, how do I test this using 12 volts. Thank you
take two cables, and the stick them to the battery or a battery (yours or a 2. car e.g.) and then open the connection, and stick one cable in the one side, and the other cable into the other side (black to black, red to red +/-...)
if you are not sure what you are doing, you might consider letting a shop look it over..
