5 Common Chevy Blazer 4WD Problems (+Solutions)

Here are some Chevy Blazer issues you might encounter:

1. 4WD Won’t Engage or Disengage

Many users struggle with switching between 2WD and 4WD modes.
Here’s what you can do about it:

2. 4Hi Won’t Engage, but 4Lo Does

Some Chevy Blazer drivers experience issues with switching from neutral to 4Hi. However, there’s no problem switching to 4Lo. This is mostly related to a transfer case encoder motor issue. 

Here’s what could be wrong:

3. 4X4 Selector Switch Not Working

If you notice a blinking 4WD dashboard light and can’t transition between 2WD and 4WD modes, you might have a faulty selector switch — possibly with worn or cracked solder joints.

Try resoldering the joints and cleaning the switch buttons. If that doesn’t work, you might need to replace the selector switch.

4. Unusual Noises When 4WD Engaged

The causes of unusual noises after activating 4WD mode include:

5. Leaking Transfer Case

If you suspect a leak, you’ll need to check the transfer case. 

Fluid leaking from the output shaft seal (a seal to prevent lubricant from leaking) could be due to an overfilled transfer case or faulty seals. You’d need to drain the excess if it’s overfilled or replace the faulty seals.

However, if there’s transfer case fluid coming from between the two transfer case halves, you might need to remove and reassemble the part to reseal it. This is best handled by a professional.

But how much would these fixes cost you?
