2001 Chevrolet Blazer Problems

ABS Light Due to Brake System Control Unit Failure

The Anti-lock brake system (ABS) control unit may fail internally causing the ABS warning light to illuminate.

Instrument Panel Lights Flickering and Exterior Lights Intermittent

The headlight switch used on the Chevrolet Blazer is known to fail through normal operation. Since the headlight switch is also integrated into the interior lights, a malfunctioning switch can cause issues with interior lights as well.

  • Symptoms of a failed headlight switch include:
  • Headlights and taillights failing to turn on or off
  • Interior lights flicker, or fail to turn on or off
  • Gauge cluster lighting off or flickering with headlights on
  • Parking light malfunctions  

This issue is well known with General Motors Trucks and SUVs, and is solved by testing and, if needed, replacing the headlight/dimmer switch. Bad grounding wires at the tail-lights, and dirty/corroded tow package wires can also lead to some of these issues. 

Transmission Output Seal May Leak Fluid

The transmission output shaft seal may leak transmission fluid. On 2WD models, this leak can cause the transmission mount to become oil soaked, which will require replacement of the mount along with the leak repair. On 4WD models, if this seal leaks, the fluid will leak into the transfer case, causing it to become overfull.

I had this since it came out never had a problem, kept up with preventative maintenance, got all the options for the LT and recently added some new upgrades like a camera system, new radio with ipod integration. Ever since I bought it, never had to replace transmission, engine or any other major part. I'm proud to say that I even was able to tow a load larger than what it was capable of. As far...
Purchased in 2007 at 70K. We now have 120K on it. At 110K got a hole in the radiator. When the radiator was replaced, the transmission fluid connection was not secure and immediately popped off, causing transmission to be destroyed. The shop gave us a new transmission at their expense - a great example of how some shops still stand behind their work (thanks, Ewers Tire!) We've had to have a...
