Question about 1998 Chevrolet Blazer

1 Answer

Two Things: Wipers randomly don't work at all, or go too long and fuel gauge not working.

My Blazer has been having many electrical system issues since only 35k miles, one after the other. First, similar blinking sound issues like other post...

For long time, I've just been living with it since dealer fixes cost sooooo much, my wipers are completely random. In Norcal, I've been lucky they worked in rain 80% time, but some storms without wipers were scary.
1) Won't do anything hitting on switch at any rate, or with sprayer - just dead.
2) Won't stop at normal number of wipes, go 5-20 extra wipes.
- almost never work correctly.

Also, since about 80k my gas gauge doesn't work - at full it reads full. It goes down to about 3/4 tank what seems accurately. At that point, it starts going back up to full. Sometimes when I turn on the car, the gas gauge jumps around randomly. This got worse... at 80k, used to work until at 1/4, then would climb. Over the miles, it got worse and worse so now it becomes wrong at 3/4 or little more. I have to track gas tank by my "computer" that gives me compass, temp and mileage/gas used/range. Luckily I have LT with this feature.

Hi chuck. I red your problem.
I anderstand your problem is electrical.

OK.On Chevy wiper motors have a defect " I called"
But the problem is the Wiper module or Wiper board,
That goes inside of the wiper motor. it's cost on dealer about $ 40 or around 20 to 35 on Autoparts.
Is easy to replace it. no need to take out the wiper motor.
Just remove the little torx screw on the black tap and take out
You will see the module.
I hope this work for you.

    Sorry I forgot the problem with the fuel gauge.

    The problem on this come when the fuel sender on the fuel pump assemble come damage due to wear.

    And for fix this you need to replace the fuel pump assemble.

    Is other common problem on Chevys.

    NOTE: if you gonna replace Don't put a cheap, Buy a A/C delco or Carter, if not they come damage soon.

    Thank's for use fixya.

not sure if this is your problem or not but in my blazer my gauges would just start going crazy at random times and sometimes the my speed would be accurate and other times it would be 10 mph off and the odometer and prnd123 would work sometimes and other times they wouldn't. after a lot of trying things I finally found the solder on the gauge cluster broke loose specifically at the PRND123 or the odometer I don't remember witch. I had to look at it under a magnifying glass and I could see some very slight movement after I soldered it back together it has been working great and I have not had any other problems with it. hope this helps you out.

Dear Sir, I need help to fix engine over heating of my 1997 chevy blazer. For your additional information the engine is not over heated during running whenever I turn on the air conditioning. Thank...

Many things can be leading to an overheating issue.

Is your cooling system full of coolant and is it still good. I simple gauge can be bought to test your coolant condition.

Is the fan moving when running, if it's electric check the relays.

Another odd thing may be your thermostat is not opening.

Check things things and get back with me if this dose not solve your issue.

Good luck.

My wipers work when they want to don't always work when it's raining. Is there a recall on the windshield wiper motor for a 1997 Chevy Blazer?

I don't believe there is a recall but I've replaced a lot of the wiper control modules [glorified circuit board] on top of the wiper motor for similar problems. Something in the circuit board goes bad and causes the wipers to malfunction randomly. There are other things that can cause wipers not to work but I'd look there first

1994 Chevy Blazer problems. Car starts and runs for a bit. Dies later and won't restart. Next day it will start and dies later. Have changed EGR, O2 Sensor, Fuel Pump three times, fuel filter. No luck....

Have you checked the battery after it died. I would check and see if the alternator is putting anything out. If its not, then i would look into the pink and brown ignition wire that runs the alternator and gauges and such. If any problems with this wire those very things happen. Hope this helps.

Gas Gauge or Sending Unit

more than likely it's the gauge it sets in a circuit board and sometimes the contacts get worn and with vibration it voltage spikes it and then it fails. very seldom is it the sending unit in the tank. please rate this...thanks
