Blower Directional Issues by pawlakjl
Apr 14, 2008 (10:07 pm)

I have a 1999 GMC Jimmy - It has been in the shop all winter for problems with the blower not changing to defrost or the floor properly. I can get hot air to blow at my face until I am sunburnt but I can not get it to change to any other setting. I can not seem to find anyone to figure out what hte problem is. One mechanic said it was the vaccum hose and he replaced it said it was fixed BUT it was NOT. I really can't afford to take it to the Dealer. You know I would pay a lot of money and I don't want to spend that kind of money on an older vehicle. Please any help or suggestions would be greatly appreciated. Also, I smell antifreeze in the car when the blower is going. I understand the heater core needs to be replaced. Is it really a difficult job or is it just time consuming since the dash has to come out. Also what about a manifold intake gasket? Hard job or what?

2001 Blazer Differential Fluid Check by frankkff

Does anyone know how to check the fluid in the rear differential of a 2001 Chev Blazer. I was attempting to drain the grease and replace with synthetic grease but I can not see either drain plug or fill plug.
Anyone have advice?

Generally, you pull the rear plate and clean out the differential. Put on a fresh gasket and bolt it back up. The add fluid until the level is even with the bottom of the one hole on the side and you are done.
 
The plug is just above midline of the differential, on the passengers side.
 
You can get a suction draw and get the fluid out that way, but you won't get all the fluid, and you won't get the small amount of metal out of the bottom of the diff.

Your blower issue should have been an easy fix... even for a dealership... and they would have had the right part. Sometimes it is best to go to the dealership... they have had experience with these issues... yes you might pay more... but better in the long run. The motor... electrical... that drives the diverter door... up for defrost... down for floor heat... is either dead... or the switch is messed up... or there could be a simple hardware issue... like a broken lever attached to the electric motor and the door. See if you can hear something moving... near the center hump... and on the driver side... when you turn the selection knob. If you hear something... then chances are the motor is working... but the diverter door is not moving. Most likely... the issue is with the control switch... I believe the motor functions very well.
 
I hope this helps... TJ

2000 blazer fuel system by jakedog1

Have a ruptured fuel line I'm trying to replace....Is there a trick to the fittings on the fuel lines or is a specialty tool required?
Also, what is the black box at the rear drivers side that two fuel lines run into? I know its not the pump.
 
Thanks

Some of the fuel line connections require a special tool. Your auto parts store may have one that they loan out.
 
The little box at the back is the evaporative emissions charcoal canister. Filters the fumes from the tank and fuel injection.

Column Shift Cable by quantumtouchfl

Has anyone experienced a very hard (jammed) shift lever on the column? If so... do you know what caused it? The shifter cable somehow became kinked. It happened to me after the transmission shop replaced the selector shaft seal on the transmission.
 
Thank you,

Radio/Climate Control Lights by jpmccr

Ok this is a multiple question question. What would make the lights in my 2001 Blazer go out? Talking about the lights for the radio, the control buttons, etc. Pretty much the lights for the center dash console. Not all of them mind you. They seem to be going out a little at a time. Part two is can they be replaced??? I would love any help . . . . .

U-Joint or Rear Differential failure? 98 GMC Jimmy by pilot1122
May 08, 2008 (6:04 am)
Reply
98 Jimmy 4.3 Vortec 4 WD. Vibration appears to be comming from the rear end at 30 mph, then dissappears above that speed. At slow speeds up to 30 mph, a whirring sound is heard from an undetermined direction. At speeds nearing 60 mph, a rear vibration is felt again.
 
Would this be the beginning signs of universal joint failure or rear differential failure? any takers??
