#3245 of 3676 4X4 Troubles
Jul 30, 2008 (11:10 am)
I have a 2001 Chevy Blazer, it keeps locking itself into 4 Lo. I put it back into 2 HI but today, it locked itself into 4 Lo and wouldn't come out. The Service 4WD light is on and my mechanic kept pushing the buttons on the dash until he got it into 2 Hi then he unplugged the 4X4 pushbutton switch on the dash. Is this a costly item to replace???

My 1998 Blazer has problems switching from 2wd to 4wd. When the 2wd light is on I can switch to 4wd sometimes. The 2wd had switched to 4wd by itself when starting the car. When this happens the buttons stop working and the car is stuck in 4wd. The lights are unpredictable, sometimes on sometimes off, they change while I'm driving. I've been told to disconnect the battery, ground the cables, reconnect the battery if I push the buttons and nothing happens. Most of the time this works, but you can emagine the headache this is! I'm looking for a fix that doesn't require several failed attempts at finding the right solution. We all know how expensive and time consuming it is to keep guessing at what the problem is. Anybody had this problem?
#3247 of 3676 Blazer Starting Issue
Aug 03, 2008 (11:34 am)
2001 Blazer 4X4, 120,630 miles. Problem: refuses to start. New battery, altenator; starter is turning over engine. It sounds like it wants to start however it will not "catch". Where should I check first? Wires, plugs, distributor cap, rotor??? I have changed any of the above in a while (really long while). Any ideas would be greatly appreciated!!!!!! I really need to get this thing up and running.

Now for the strange thing. It sat since Friday morning when this all started. It didn’t start. We took off for the weekend in my wife’s car and came back Sunday. Tried again. No luck. Got up this morning and again it wouldn’t start. Then I got thinking did I hear the fuel pump “whine up” as I call it. Well I tried it and sure enough it was, which to me meant at least the pump was doing something. I did it twice. Then just for grins and giggles, I tried to start it. It fired right up!!!!!!!!!!!!!! Have no idea unless my fuel filter was clogged and I broke something loose. So this weekend I am going to replace the fuel filter and run a fuel treatment/injector cleaner through the system.

Ok, it has to be the fuel pump. It did start and ran great for three days. Then the same thing. I did get stranded but it was at work so no foul. I finally got it to turn over so the wife and I went back to my office and I drove it home. Now that it is here, I can search for a fuel filter and if I am lucky have it start just one more time so I can drive it to the shop and not have to have it towed there. Any suggestions on where to look and what a good price would be? Thanks.

NAPA has good products. The NAPA premium 65 lb. output fuel pump is $95 including seals. NAPA fuel pump strainer is $8 and fuel pump wiring harness is $10. All those items should be replaced when the fuel pump is replaced or the new fuel pump will prematurely fail again.

I can change a 1991 Blazer headlight blindfolded. They can b e replaced from the front just like all GM headlights have been replaced as far back at 1948. All you need is a wire coathanger with a little hook on the end, a long, thin, flat-blade screwdriver and a little stool to sit on. Reach in with the hooked-end coathanger to pull out the headlight spring and unhook it from the headlight retaining ring, unscrew the two headlight ring attachment screws from the headlight ring , pull out the headlight and unplug it from the wiring harness. . Then reassemble it in reverse. Don't remove or unscrew the headlight aiming screws.
You probably have the "new and improved" headlight assemblies.. I have never replaced the whole headlight assembly on one of those but the little bulb is the twist in type that twists into the socket hole in the headlight assembly. I assume you are having a problem finding the headlight socket hiole. The headlight bulbs on the other later model cars I have replaced does not require removing the whole headlight assembly. Don't touch the new bulb with your fingers or it will prematurely fail. Those little twist in headlight bulbs burn hotter and the oil from your fingers will cause the glass to fracture.

What year model? The newer (96 and newer) just use two tabs that are pulled up and release the headlight assembly. Bulb change takes less than 5 minutes.
