A/C radiator fan on cold start, frequently on.

[mikez71]

My AC radiator fan runs too much, not the engine cooling fan.
Once it goes on, it usually won't stop for several minutes, even when I turn the AC off.
Seen pressure hit 180 psi on a cold start, drops off but my noisy fan stays on awhile.
Pressure usually in the 60 psi range off, around 140 when running.

Something stuck open or leaking? I may redo a bunch of AC stuff...
compressor noisy, but I dont think I will change evap core...

Suggestions? I am considering to unplug the fan temporarily this winter.

Fan noise is killing me, yea I'll get a new one, but it shouldn't be running this frequently?
And lately my brake pedal started squeeking
Like old people talking about aches and pains, my 13 year old truck acts like a 65 year old man.

first... get a piece of cardboard and put in on the floor under the pedals, then get a spray can of lithium grease and spray up in the hinge area of the brake pedal arm.
leave the cardboard there for a day or two because inevitably some of that grease will drip down over a day or two usually overnight while it sits.
that should solve that problem

2nd the fans should not be running separately, both should run at either high or low speed.
there is no left/right control on this gen. unless you have somehow changed something from stock or if it is a hybrid system, those I believe have 3 speed options.

I would pull the fans and have a look at the connectors and harness or you can easily pull each harness off of each fan and look at it with a flashlight, look for anything burnt.
the ac system very well could be a issue, but that is separate from the fans not both running.
***specifically take a close look at the fan that is not running on the cold start
