#2446 of 3676 1997 Blazer Electrical Problem
Jul 07, 2006 (3:01 pm)
Have an interesting problem with my 97 Blazer LS (4.3L V6). It has about 92,000 original miles on it. Unlike apparently a lot of folks, mine has been essentially trouble-free until now. Last Saturday took it on a trip of about 200 miles each way. Everything was fine until about 40 miles from my destination. I was on the interstate doing about 65 mph when the engine suddenly appeared to lose all electrical power momentarily then recovered and everything returned to normal. Did that 4 or 5 times over about 5 miles. When it happened, dash voltmeter dropped to near 0, gas gauge went squirrely and speedometer surged. ABS and Airbag lights came on and remained on. Exited the freeway and pulled into a Chevy dealer near the exit. Service and parts were closed. Checked under the hood and everything appeared normal. Started up the engine and everything appeared normal. My thought was to try and make it to a town where I could have the alternator tested. However, everything continued to be normal so I continued on to my destination. On the return trip a few hours later, everything remained normal until I was about 40 miles from home when the same thing again occurred twice. The engine recovered and I made it home with no further problems. The following day I replaced the alternator and the engine ran normally. The vehicle sat idle for 3 days. Yesterday, I drove it on some local errands that required shutting down and starting it again several times. Again, no problems. After returning home and a few hours later, I tried to start it and it wouldn't. Starter turns the engine but there doesn't appear to be any power to the instrument panel. None of the lights or gauges turn on with the key in either on or start. I would certainly appreciate any guidance or suggestions from anyone who may have had the same or similar problems.

Easy one - known problem part is the "97 ignition switch", under $100 at most stores. This is the wiring and connectors in the column, not the actual tumbler/key. Some bad internal connections and most power runs thru it so that's why it dies and restarts. Do a search on this and you'll find lots of info on the web.

2 questions. I have a 97 blazer and it seems to be making a squeaking noise repeatedly in warm/hot conditions. With the windows down it sounds like it is coming from the rear right hand side of the vehicle. my guess would be something to do with brakes seeing as how when i hit the brake even just slightly, the squeaking stops. Not sure how else to describe the problem, because its only audible when traveling 25-???mph.
Also, I am selling this blazer, and would like to find a good price for it, 97 4x4 brown, cloth interior(brown) premium wheels - clean flawless in nearly every way except the following small problems -
^the problem listed above^
driver side door has a very slight ding in it, hardly noticeable.
driver side door lock doesn't lock with power locks, must be locked manually.
tread approximately 50%
some positive things about the car include
kept well & clean by mature & loving owner
Roof holder thing
1 month old alternator
from what I have seen the approximate price would be 4500 - 6,000$ am I wrong? edmunds says 4g private party, KBB says 5.5g private party, whats up with this

97 has rear drums so check the pads and make sure you place a dab of grease behind the pad point where it contacts the mounting/backing plate so it will move without hanging up. Also make sure the front discs are not worn and contacting the squealer/low indictor tab.
As for price that regional and what the local market is doing vs how fast you want to sell it - all online books are averages so good luck. Mileage is also important as well as what items you have maintained.

My 2000 Blazer is equipped with the brake replacement alarm which is designed to make squeaking/hissing noise when the brake pad is worn out. When the brake pedal is applied, this noise disappears. Mine started to make this noise at 45,000 miles and I replaced brake pads for a few hundred dollars at a dealer. 2000 Blazers have rear disc brakes. This repair seemed to be a normal wear and tear maintenance. I hope this helps.

I know it is a small problem but it really bugs me...the digital temp gauge is out of wack. It shows 135 todat (i know it is a hot PA day bu this is just silly) Anyone know where the sensor is? Or if something else may be wrong?
#2455 of 3676 Blazer AC Trouble
Jul 10, 2006 (11:05 am)
I have a 2000 chevy blazer with auto climate control which stopped working altogether. The ac compressor runs all the time (cycles) no fan, the controls to change the vents (floor,defrost,dash)don't work, rear defog doesn't work,
and temp doesn't change. All the fuses are good also. Is there any help for this?
