Replying to: bradtown (Dec 09, 2007 4:55 pm) Original Problem: #4 (Gauges) Fuse would blow every time I started my '96 Blazer, daytime running lights would go out, alternator would get bypassed, car ran straight off of the battery... basically, I was going nowhere... Incorrect Solution: Here are all the things I replaced in the hopes that it would solve my fuse blowing problem...But none of them were the correct solution!...alternator, ignition switch, 4WD actuator, shorted wire, loose ground wire, tumbler, etc. (NOTE: none of these were the "correct" solution to my problem, so if your #4 fuse is blowing every time you start your Blazer, I'd be willing to bet that replacing any of the afore mentioned parts won't solve your problem either.) Solution: 4WD Indicator Light Switch (or at least that's it's the technical name GM has chosen for it). (OE# 15598481) It's related to the 4x4 system and is located on the "shift cable housing" (black cone shaped object that houses the cable that engages the 4x4 when the actuator is engaged by pressing the button on your dashboard). This Indicator Light Switch looks like an electric plug, and it is located right in the area of the front axle on the driver's side of the car. Actually, the switch is on the side of the cable housing, which is bolted (with 3 bolts, in a triangular base) to the front differential. Don't worry if that all sounds confusing, because I'm no expert in clear technical explanations. So instead, I've taken some alternative measures to help explain... Here are some pictures that will hopefully help explain the location of said Indicator Light Switch better than any I attempt I can make using 1,000 words.....  (click on photo for larger size) The above picture is what it all looks like when you lay down under the front of the car with your head facing the rear of the vehicle and your feet sticking out from the front. When you're under the middle of the car and under the front axle, turn your head left (towards the driver's side) and this is what you should see.  (click on photo for larger size) The above picture is what it looks like from the front, looking towards the back of the car.  (click on photo for larger size) And finally, the above picture is of the culprit itself. The nut is rusty in the picture because that's the old (broken) one I pulled out of my truck. If you'll notice on the other pictures, the nut is a shiny, new brass color. You'll need a 7/8" box wrench to loosen the sucker, but it's not tightened too much, as the cone it's attached to is made of plastic. Bottom Line: $20 part, 10 minutes of work, and my Blazer is now fixed! And that's the entire story! I'm hoping that anyone who has a similar problem in the future will find this post useful and will also avoid wasting hours of time trying to figure it out (like I did) and/or spending obscene amounts of money on a mechanic. Good Luck & Keep on Truckin'!! Leo and me

Anybody change the motor mounts? It looks like I have a broken mount and wanted to get input on the busted knuckle count before I decided to take it on. Thanks, Jim |

Replying to: tidester (Dec 11, 2007 12:03 pm) I should also add that although that solution was what worked for my particular problem, I realize that it's not an absolute solution for everyone who has a problem with their #4 Gauge fuse blowing when they start their Blazer. There are many circuits that lead to that particular fuse. I found a listing of which systems are linked to the #4 fuse in my Owner's Manual that came with my Blazer, but that's for my 1996 Blazer. I'm not sure about the other years. Bradtown and I have been exchanging e-mails these past few days, in the hopes of being able to solve his problem with the #4 Gauge fuse blowing on his 1995 Blazer. I'm hoping he'll be able to post an update on what he's finally discovered was causing the problem in his truck. Needless to say, it wasn't the 4WD Indicator Light Switch that caused my problem. What he also discovered was that his '95 Blazer was wired up differently than my '96 Blazer, as far as where the 4WD Indicator Light Switch is actually located. On his '95, it's located closer to the passenger's side and actually on the front axle. So, it looks as though GM changed things around a bit just from that one year to the next. I can only imagine what other year's Blazers are like. Again, I want to restate that the other post I made is only one possible solution to a fuse blowing problem. Naturally, it's always best to consult a repair manual for your specific year and model and follow your best judgment when solving the problem.

The radio on the Blazer will start to turn off and on when the car gets warmed up. It won't do it when you initially turn the car on but after about 10 minutes it starts its problem. The off and on times vary, they are not consistent. Also, the car battery dies at wierd times. The car may go for two day or three weeks without the battery dying but it will die at some point. It may start in the driveway but die at the store. It is not a complete death either. It will click the starter solenoid or the hood light may turn on but dim. We are not sure if the battery problem is part of the radio problem. Any Ideas?

97 Jimmy....heater core has a small leak but it sure stinks up the place and scums over the windshield. So to get the heater core out for repair or replace, do I have to take out the whole dashboard from one side of the car to the other? Maybe the windshield too? Ha. seriously this looks like a bear to remove. I'm not scared to do it, just want to know how to attack. Al |

I have a 2001 Chevy Blazer, it keeps giving me code P0301 - Misfire on #1 Cylinder, I have replaced the spark plug 3 times and the wires are new. I had to replace the engine a few months ago with another used engine. I don't know what else to check. Any suggestions? Thanks. |
