    Fan speed too high means most likely that the EV fan clutch is locked up and needs replacement. Fan speed is not what the computer is commanding it to be, so the SES light is on as a warning.
  • This clutch situation is out of control...Is there a way to force a recall?

    I doubt if this would be a safety related issue, so the chance of a recall would be remote.

    i have a 04 TB, IT STARTED HAVING REDUCED ENGINE POWER LAST WINTER IN THE MORNINGS BUT NOW IT HAS STARTED DOING IT EVERYDAY AND IT IS THE MIDDLE OF JULY, IF I LET IT WARM UP IT IS FINE,(WHICH THE REDUCED ENGINE POWER LIGHT IS ON THE WHOLE TIME IT IS IDLING,) BUT THE SERVICE ENGINE LIGHT STAYS ON FOR A COUPLE OF HOURS, THE DEALER WANTS TO REPLACE THE COMPUTER(800.00) ANY SUGGESTIONS BEFORE I DO THIS
  • Any special advice to replace fan clutch? Tools?Remove fan shroud only?
  • tblazedtblazed Posts: 945
    There's more to replacing the clutch than is practical to go into here. Yes you need a clutch tool and a big wrench to get the clutch off the water pump shaft. You also have to drain the radiator part way to take the upper radiator hose loose to get it out of the way, remove a few bolts, unhook the shroud, and lift the whole fan-clutch-shroud out all at once. GM did not make the job easy. (If they had used a two piece fan shrowd like on my '88 S-10 it would be very easy, but they didn't.) If you do a Google search you should find a lot of info about doing this yourself.

    I have a 2003 Trailblazer I have a ticking noise coming from the front of the engine. I am not sure if it is one of the pulleys. It has 32000 miles onit. Has anyone had this trouble before.
  • Wiring problem in 03 fan clutch. Thanks much for the info Tblazed, I was set to replace the fan clutch when I found the black wire on the wiring harness plug was not making connection. I connected a jumper wire and now the temp is normal, ac works, and I saved hundreds of $. I hope this helps someone else.

  • I had the same problem on my 02 TB, the dealer "reflashed" the computer. It didn't work. Any suggestions would be appreciated as the mechanic unsure on how to fix it. thanks.
  • I own a 2002 TB and recently I've been having problems in the morning. The truck starts ok but as soon as i give it gas it does nothing, then the engine "catches" and then it's ok. The dealer "reflashed" the PCM? (computer) but that hasn't helped. During the rest of the day the car is fine. Any help would be greatly appreciated. Thanks.
  • Did anyone ever figure this one out? I too am having problems with the connector burning out on the driver's side low-beam headlight. I have replaced the connector a few times, and it just burns out again after a few days. Does anyone have a solution that will prevent this from happening?

    You know what YOU CANNOT FIX THE FAN CLUTCH i had the same problem you know what i did I DUMPED THAT POS AND GOT A HONDA. Gm knows its like that and i had 102000 miles on mine and not only that was that problem it was the tranny slipping, and all tranny shops said nothing was wrong. Also dealers saying that the k&n was the reason for the fan clutch. And it stalled on the highway the reduced engine power light did not even come on. Took it to a dealer to fix it mine you they put 6 DIFFERENT FAN CLUTHCHES ON AND NO SOLUTION had gmpp the computer died. So guys i suggest get out IF YOU BITE THE BULLETT YOU WILL THANK YOURSELVES FOR DOING IT BELIEVE ME I LOVEEEEEEEE MY HONDA I DO NOT WORSHIP IT BUT IT BEATS TRYING TO TELL DUM A....... YOU CAR IS BROKE AND THEY LOOK AT YOU LIKE YOU ARE A BUTTHOLE. SO you are NOT GOING TO BE HAPPY IM WARNING LEAVE GM PERIOD TRUST ME JAPAN RULES US
  • I too have an '03 TB with the same ticking anyone come up with a solution?

    I have replaced mine three times, I have an 03 with 116k miles and the last change was at 65k miles and my mechanic said let's try some dielectic grease in the connection to help disipate the heat. He was right and that was a few years ago.

    I know this has been discussed here before, but it's been some time and the links don't all work anymore. My external temp sensor has gone out on an 02 TB (for the mirror display), and I am having trouble locating the part on online GM parts suppliers. If anyone can enlighten me with part # or any info please do so.

    Just bought an '05 TB EXT and am experiencing what seems to be driveshaft noise. Upon accelerating from a stopped position, there's a ting, crackle type noise. Told the dealership and they checked it out and said GM is aware of the issue and there's nothing that can be done. Anyone else experience or hear of this problem? :confuse:
  • When attempting to place my 2003 TB in AWD or 4WD, all I hear is a grinding noise. Any idea what the problem may be and how much a repair may cost? Thanks in advance.

  • It's not a driveshaft noise....it's a sterring shaft noise. Where the steering column extends down from the sterring wheel to the actual steering gearbox, it is a two piece shaft that slides inside each other to extend and shorten with the front suspension. GM packs these with grease from the factory, which promptly just gets pushed out. They have tried several fixes over the years, all which proved to be temporary at best, and not at all cost-effective for GM, so now they just recommend to do nothing. This problem plagues MANY GM models of trucks and SUVs. Used to work at a dealership, own a 02 4wd TB, and have been through all this with mine.
  • Hey guys,
    My friend hit a deer this past weekend and it busted on the plastic front grille in his 2003 Trailblazer. He said this was a snap in grille.

    Does anyone know where he could find a replacement? And, is it just that easy to snap in, or does it require professional installation?

    Thanks,
    Scott
