I am familiar with this code (I am a dealer tech) and the repair is to replace the electrically controlled fan clutch, it has failed, fairly common problem, it is around $150.00

Hello I have 2002 envoy check engine light is on!! O riellys could not get any codes!! Engine idles and switches gears fine its just hesitant and is making a fan noise constantly like when u take off...

If the check engine light is on, there is a code, or codes, lodged in the computer's memory. Try having your vehicle scanned elsewhere. They might not have done it correctly at OReilly's.

My fan clutch is trying to go dead and it made my service engine light come on and now my reduced engine light came on what should i do

First you need to determine what the fault codes are that are setting the check engine light, if it is pointing to the fan clutch, have it replaced. But I don't think a bad fan clutch will set the reduced engine power light, there may some other things going on, the codes should help.

There a lot of aftermarket fan clutches out there that just don't hold up. Purchase either a GM part or a Dorman replacement.

1 have 03 envoy,6cyl,have replaced viscouis fan,fan still runs a lot, dealer has checked twice all ok

Do you have the check engine light on? If a fault code of P1481 or P1484 is coming up with a scanner, the fan clutch is bad.

I have a service engine soon light and the code that appeared when check is 1481, do you know what this means?

Service Engine Soon (SES) or Check Engine Light On, DTC P0480, P0526/P1481/P1484 Set (Replace Engine Cooling Fan Wiring Harness) #05-06-02-012B - (10/19/2006)

Models:2004-2006 Buick Rainier
2002-2006 Chevrolet TrailBlazer, TrailBlazer EXT
2002-2006 GMC Envoy, Envoy XL, 

Some customers may comment that the Service Engine Soon (SES) or Check Engine light is illuminated. This condition may be intermittent and upon investigation, the technician may find either DTC P0480, P0526, P1481 or P1484 set.

This condition may be caused by the cooling fan harness chaffing against the plastic guide it routes through. This contact may damage the insulation of the wires enclosed in that harness.

Replace the wire harness: 
Part Number 89024920 Description Harness Assembly, Engine Cooling Fan Wiring

Good luck and keep me posed.

Tires are tires. As long as the correct size is used for your vehicle you can use snow tires on any car/truck/SUV
