Cooling Fan(s) 101
I am asking what the normal operation is with a 2002 TL.
There are 2 cooling fans on this car, passenger and drivers side.
I just replaced the drivers side fan. It is working very well now.
My question is about the correct sequence for their operation.
On my car, when the AC is on BOTH fans operate. I understand that is
the correct function. When my AC cycles for what ever reason, BOTH
my fans shut down. I can get both fans to come on if the AC is
off and the car is idled for a long time.
Since there are 2 fans basically operating independent of each other, I am
researching what triggers them on and off.
Since I replaced the drivers side fan, the temperature gauge is rock steady
at 2 clicks below half way.
Thank you.

Im not sure if that is the correct sequence but I have a 99.
Passenger side is condensor fan and works to keep compressor cool in a/c operation.
Driver side is radiator fan and cools coolant.
Both fans may operate when the engine is very hot to help with cooling the engine.
I think the 99's are a lil different but the fans operate the same way. Idk

Check out my recent troubleshooting thread. Lots of good info in there.
