    Radiator Fan Issue

    I was wondering if I should invest into a copy of the factory service manual or not, seems like it might help. One last quick question, in that screen grab, which one terminal 87?

    Radiator Fan Issue

    Have been too busy with work and family to work on this, but did try something new today. Turned on the car, AC off, both fans start at normal speed when car warms up. Turn on AC, right fan stops and left fan goes into highspeed. Turn off AC, right fan turns on, left fan slows down to normal...

    Radiator Fan Issue

    Thanks! That is exactly like the 1aauto video I found describes it. At first I was worried about air in the lines but I see that is not an issue.

    Radiator Fan Issue

    Mine are the 5 bladed ones like in your picture. I will try that first since it would be easy, will wait until Monday night though. Want to call a few dealer part departments see if they have the radiator fan harness that has been known to go bad. Do you know the part number for the harness...

    Radiator Fan Issue

    Thanks, I saw your post here https://www.tahoeyukonforum.com/threads/electric-fan-mods.100757/ Was hoping it would be that easy but I guess not. There is a youtube video showing how to take out the fan shroud assembly, not too painful. Was only concerned about the transmission cooler lines...

    Radiator Fan Issue

    Anyone know if the fan motor can be changed without taking the radiator fan shroud assembly out? Trying to determine if the fan motor can be accessed from the aft of the radiator shroud. Thanks!

    Radiator Fan Issue

    Guess it is not solved yet. Issue came back, although the right fan does work more often now. At start up only the left fan works, after driving the right fan turns on. I will buy a new fan harness and try that first (if it is something that is just plug and play) and then a fan motor.

    Radiator Fan Issue

    Doh, engine fan fluid, how could I have missed that! On another note, the problem has been solved. Replaced all 3 radiator fan relays and both fans now turn on/off in sync. Outside inspection of the old relays shows no signs of damage, wear or melting. Thank you mikeyss!

    Radiator Fan Issue

    Thanks everyone and especially mikeyss. I will get new relays tomorrow (just found out the parts numbers and will call the dealerships to see if they have it). The current relays look find but for $25 or so it might be worth trying. If that doesn't fix it then I will get a new fan motor...

    Radiator Fan Issue

    I have searched the forums for the past few days, and google as well, only thing kind of close is this thread but it isn't quite the same: https://www.tahoeyukonforum.com/threads/electric-radiator-fans-running-more-than-usual.84960/ I have a 2011 Tahoe 5.3 LT 2wd with towing package. Now that...
