#84 of 104 My Trailblazer is Possessed!! by ticadoo Jun 30, 2009 (6:00 am)
My 2003 TB EXT just turned 76000 miles. To look at it from the outside and inside, you would think it was a perfect truck! This has to be the strangest-acting vehicle I have ever had...and I am getting to I am afraid to trust it...but I am stuck...I lost my 2nd job and can't afford to replace it.   Last week I was coming home from 2 hrs away (family member in hospital)..on the interstate...and the windshield wipers came on by themselves...switch was off and it was NOT raining. This has now happened three times.   This past weekend, I stopped to get gas (another 2 hr trip), turned the engine off..key was out of ignition, I was pumping gas...kept hearing something..the rear A/C was on and blowing! So, in addition to putting over $100.00 worth of gas in my truck last week (16mpg)...I have all these strange things...   Two weeks ago I had to replace the water pump..$400.00. Now, when I start the truck and get ready to take off...it sounds like a jet plane trying to take off. I have people stop and look at me....I guess it sounds like I am getting ready to "speed" off...but I'm not... What could this be?

Replying to: ticadoo (Jun 30, 2009 6:00 am) It's the dreaded fan clutch!   Check out all the past threads and you'll find that many of us have had to replace the engine fan clutch. And your right, it sounds like a jet engine.   Good Luck Texas   . Replies to this message: ticadoo (Jun 30, 2009 6:35 am)

Replying to: ticadoo (Jun 30, 2009 6:00 am) The others are correct for the "jet plane" sound. I had it and it sounds like a harrier taking off. Your fan clutch has died. I replaced my own. If I remember correctly the clutch was somewhere between $150 and $200. You have to disconnect the transmission coolant lines and then remove the radiator to give you enough room to replace the clutch. With a friend helping it took us about 1.5 hours to replace it.

Replying to: nutrinoman (Jun 30, 2009 8:09 am) How long are these supposed to last? I had mine replaced just over a year ago.
#90 of 104 03 Trailblazer can't get key out! by jspr363 Aug 09, 2009 (3:42 am)
Hi gang 1st time posting. The key will not turn to off position(where you can remove it) it stays in the aux position keeping dash lights on and running down battery overnight, everything else is ok. It all started when the shifting colum was accidentally moved to park while the car was rolling slowly ahead. The transmission seems to be fine goes into all gears and park no problem. What interlock should I look for that is holding that key from coming all the way home? thanks Jon
#91 of 104 Oil light by rpowers Sep 09, 2009 (5:14 pm)
My oil light stays on for 20-30 seconds after the engine starts (05 TB) my brothers 05 is now doing the same thing - both have about 40,000 miles on them, have had oil changes at 3000 miles - no leaks - oil level is perfect. Is any one else having this - or has anyone found the cure? Replies to this message: tmirgliotta (Nov 04, 2009 3:39 pm)

Replying to: lmgranger69 (Oct 07, 2009 3:34 am) The battery is probably bad.
