#3193 of 3263 Re: 1992 chevy blazer [enzane] by alesi64 Apr 11, 2008 (11:56 am)
Replying to: enzane (Mar 30, 2008 6:17 pm) Hi,   I just fixed a friends 99 blazer that sounds like it had the same problem. Old fuel pump died and she had someone install a new pump and also a new filter. Then it began to run/studder like yours.   It took me a while to figure out but here was the fix for her car (runs great now). The new filter that she had installed was the wrong one. Looks identical to the correct filter but either Autozone or the mechanic messed up. the in flow direction and outflow was reversed on the new filter. I found the correct filter, replaced it, and now the car runs fine.   Crazy, but check your filter and make sure the outflow (should be stamped on the metal "OUT" is pointing toward the engine. I saw the old/incorrect filter and the new filter side by side and they look identical except the flow direction "OUT" was reversed. I think GM may have changed the guts inside the filter and may have a one way valve in the filter that is starving the engine if the wrong one is used.   Hope that helps.   Dan
#3194 of 3263 hatchback will not open by jefforyb Apr 12, 2008 (12:59 pm)
Hey - I have tried everything to open my hatchback; I tried the push button inside the car; I tried opening it with the key outside the car, and I even tried manually to open it but to no avail. It just won't open; I even checked the fuses. What to do; do anybody know? --jefforyb--

Replying to: merlynxx1 (Apr 13, 2008 6:37 am) No. There are no lights on the dashboard at all. The only lights that comes on are the ones when I start the engine .

#3198 of 3263 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?

#3199 of 3263 2001 Blazer Differential Fluid Check by frankkff Apr 17, 2008 (9:30 am)
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? Replies to this message: jlflemmons (Apr 17, 2008 9:00 pm)

Replying to: frankkff (Apr 17, 2008 9:30 am) 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.   Jim

Replying to: pawlakjl (Apr 14, 2008 10:07 pm) 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
#3202 of 3263 2000 blazer fuel system by jakedog1 May 02, 2008 (6:05 pm)
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 Replies to this message: jlflemmons (May 02, 2008 7:22 pm)
