Check and see if your vehicle has a drive shaft center support. (carrier bearing). Make sure it is not dry that could be your problem or one of the front u-joints.

Please explain the problem in detail. In general these clusters have many problems mostly with the instrument displays, the best thing to do is pull the cluster out and have it rebuilt with the newest improved parts. Repair centers are all over the web, just google it.

Do you have auto locking hubs on the front wheels, or manual locking hubs?
If you have auto locking hubs chances are they are not engaging properly and will need to be removed and spline sets checked for broken teeth on locking hub and locking shaft.
If you have manual locking hubs then check that they are firm when turning to engage them in the lock position.If they are light when engaging them to the lock position then they my have broken/worn out the locking hub and spline. Also check that the engaging spring inside the hub has enough tension to engage the hubs they may be broken. If the hub are all ok then you have a problem in the transfer box, where the 4WD lever is not meshing the transfer box properly. Hope this helps, let me know how you get on.

my experiance has been to find a cracked ignition coil, to check this you need a hande triggered spray bottle with water, open the hood and locate the coil start the engine and spray the coil down with a mist look and listen for an electrical arch or if the truck simply shuts off replace the coil and be carefull(its never happened to me) you dont get shocked

Replace your A/C Actuator. most common problem is that the heater vents get stuck in the closed position blocking the heat from entering the vents. I just replaced mine in my truck and it works like a champ now.

I think i may have an answer for ya...Is your truck blowing air at all? if so its not within the blower...the problem is actually the a/c actuator. a little bit cheaper and easier to install...had the same problem with my truck...replaced everything but the actuator which cost a crapload of money and found out it was the actuator. your truck may require an upper and lower so check with local auto parts store...average price run about 60.00 for each.

Joey i had a similar problem in my 2000...The problem lies in the A/C Actuator. The Actuator is what opens and closes the vents, when the vents are open it allows hot air to flow through and when thier closed it prevents hot air coming in while air conditioner is running. depending on the year some vehicles require an upper and lower actuator. they are fairly simple to replace, and dont take much time. most actuators are located under the control switch box (radio, a/c dials) parts run about 60.00 each.

Did removing the HVAC fuse help your problem with the AC? Thanks

2002 GMC Sierra... | Answered on Jan 24, 2011

Well actually I don't think the bearing damaged the whole thing, Proberally they just don't want to press and and press out the new bearing cause it may not be worth their time financially.. Tell them just replace the bearing and make sure to grease it properly..

You see they will need to take out the entire assemble, then press out and press in the new bearing as opposed to take out and replace the entire assembly which they can then fix and resell. So just have them change the bearing..

Bet you need to get some new shocks may just be one whichever side takes it the hardest.
