SOURCE: 2006 Chevy Trailblazer - winding noise

I went to the dealer to check on the price for the idle pulley and they said that was waht the problem was. The quote from them was $99 for Labor and $38 for the pulley..Solution $18.00 at the parts store and 20 min from my hubby and it is fixed. The only problem with the pulley form the auto parts is that the original washer won't fit in the hole so we had to but a seperate washer. Runs great now I just have to find a solution to the gas gauge and fuel sensor.

SOURCE: 2002 trailblazer making loud humming noise when driving

When you turn right - you're taking weight off the right wheel.
If the noise dissipates - the passenger side wheel bearing is most likely to blame.

Thanks

SOURCE: 04 trailblazer AC leaks

Rather than pay the dealer $350+ to fix this, I found the "L" shaped drain hose behind and interior to the front passenger tire (I let the car idle with the AC on and waited for a drip. On my back on groud I reached in and found the drain line and it came off i my hand and about 4 oz of water and some decayed matter floowed out. I reaced back in and found the hole to which the L line was attached. It was a rubber fitting on the end of a metal pipe. The fitting came off easily and then about 8 oz of water flowed out (carpet had been soaked for two days). I reattached the L drain line and noticed that inside the fitting was about 1/4 tsp of "mulch" - decayed leaves, pollen, etc. Reattacted the fitting and water now flows freely out the drain. And yes, its a very high humidity area - Houston, TX. And if you live anywhere near here you know about the intense yearly dispersion of Pine tree pollen. I thisnk that accelerates the blockage. Happen about every 2 years. (Third time for me. First two I let the dealer over charge me for this effort. BE SAFE WORKING UNDER YOUR CAR!

SOURCE: Where is the cruise control fuse in a 2004 chevy

Gotta tell you, this question had me a little confused. Below are 2 wiring diagrams for you. One is for the cruise control circuit and the other is for the air conditioning circuit. The reason I gave you those is because it seems according to the wiring diagram in the cruise control that the fuse for the cruise control goes to the HVAC (air conditioning). According to the wiring diagram for the A/C yes that fuse also controls the ignition power for the A/C controller. In any case the fuse that would cover the cruise control is the number 30 fuse in the fuse panel located under the hood of the vehicle. Below is a picture of the location of the fuse panel and also fuse layout diagrams for the 6 cylinder and 8 cylinder engine vehicles as they have different layouts depending on the engine size. I hope this helps you and good luck.

Why won't it engage transmission?


Most likely a clutch band broke. Other parts cold have broke, but they usually grind first. Time for a rebuild. ($2000+). No shop will just fix the problem.

04 trailblazer front wheels grind after using 4wd?


You probably have a front drive splined disconnect assembly that has gone bad. This assembly engages the front differential when 4WD is selected. Below is a figure of the item, it is on the passenger side of the differential area.

What is it when in reverse the automatic transmission on a 1999 Camaro grinds?


Reverse is not "synchronized" forward gears are, so it does make some noise, try shifting to 2nd before engaging reverse to slow gear rotation and limit gear clash or grind.

96 nissan sentra 5th gear grind


Mor than likely damaged one of the planetary gear sets. Grinding in a trnasmission or rear end is a sign of loss of contact between meshing gears. Automatic transmissions engage two sets of gears internal to the trans to create a forward drive gear, changing between the gear sets creates different ratios anwhich in turn aloows for higher speeds. If the trans only grinds when in fifth range there is mopre than likely internal damage to the gears which 5th needs to operate. I would start by pulling the dip stick for the ****** and check for black or shiney material on the stick. I would then take a sample of oil from the trans by draining some from the drain plug if it has one, or possible drop the pan and check for foriegn matter in the fluid. Peices of metal shaving point to gear damage, and black material pont towards clutch wear/ damage. A worn or damaged clutch will cuase that specific gear not to engage and cause a grinding noise. Either way the concern is internal

Grinding noise when trying to start 04 Taurus about once per 40-50 starts. had starter replaced and now grinding is worse. once per 10 starts. starts on third try.


It sounds like the gap between the starter gear and flexplate is growing. The ring gear may be worn out in spots causing the starter not to engage the (shortened) teeth of the flexplate. Or the starter is shimmed too far from the flywheel ( less likely ).

The flexplate problem will require the removal of the transmission to repair.

The part itself is not that expensive, however, the labor to replace will bite you

Replaced starter still makes grinding noise..what could it be..


Chances are, the flywheel ring gear is damaged and the new starter drive gear just doesn't have enough to engage into so it spins and makes a grinding noise. If you can, try and turn the engine over a tiny bit by hand and then try the starter. If this allows the engine to turn over and start, this is probably your problem. Unfortunately, most engines come to a rest in the same spot(s) when you shut them off so the starter always has to try and engage in the worn area. The fix involves removing the transmission and replacing the ring gear...a big job.

Fourwheel drive noise when driving in 2wd noise whinning sound


This is a somewhat common problem with the 04-06 MY 4x4 trucks.

The IWE vac solenoid can ingest water, and introduce it to the IWE, or can develop a problem where it does not keep constant vac on the IWE ends, and the gears hang part in ( grinding ).

You can check the IWE solenoid to make sure it will supply VAC to the IWE ( vac keeps the IWE out, remove vac, and the spring will engage it into the gears ).

You can check the vac lines to the IWE, and the solenoid, but I hate to say the IWE solenoid needs to be replaced.

Here is a link to a PDF version of the TSB with the part number for the updated IWE solenoid that the 07& 08 MY trucks have.
http://my.voyager.net/~sscully/file_tsb06_08_15.pdf

Here is a block diagram of the IWE layout, so you can check the vac lines. Hope it is as easy as a cracked vac line. Also check that the vent tubes are clear, and still up into the engine compartment.

I have a 5speed manual transmission and it sounds as if the gears are grinding while driving in all gears. The transmission shifts ok, and does not slip, just makes the noise. Can the gears be out of...


The clutch needs an adjustment. What's happening is the clutch isn't completely engaging while you shift, causing the grinding. Once properly adjusted, the grinding will disappear.
