Ok, I have a weird problem going on with my 1996 Blazer. I have had 90s GM products in the past so I am familiar with the ABS system and its quirks. This one seems a little different.

The parking brake light on my dash stays on all the time. Now I have had this same issue where the ABS light is also on when you have an ABS issue and I have also had this happen with only the P brake light when the fluid is low. I have checked the fluid and it is not low and the ABS system is working fine, light is not on and no ABS codes or Trans codes.

Could my P brake switch be bad possibly? Or maybe my brake fluid level switch?

 

I would start with the switch.
