97 S-10 ZR2 Brake and ABS lights flash

[I_Make_Ale]

Occasionally when driving my 97 S-10 ZR2 4x4, the heater fan will stop running, and the brake and ABS warning lights will flash quickly in sequence. This only takes maybe 2 seconds, then the fan comes back on, and the lights go off and stay off. It doesn't happen enough to be able to isolate the conditions that seem to trigger it. It seems like it happens mostly when I'm depressing the brake pedal, but I believe I had the cruise on a few times when driving about 35 mph too and it dropped the cruise, and I had to switch it off and on again to reset it. It stops just fine. The brake fluid appears to be full, and I haven't done any brake work for probably 6 months when I replaced the rear shoes.

Has anyone else seen this and have an idea what the problem might be?

Thanks!

Sounds like a short somewhere (maybe in the abs wireing) Get a scan tool and check to see if it has any codes.

an abs sencor could be going, im unsure of where its located, but my grandpas toyota coraolla had similar symptums untill the sencor eventually went out, they were 200 bucks for just the part

That would cause the fan to die.

Dead short somewhere.

Thanks. I'll see if I can read any codes. That might help me narrow it down to a sensor if that's what's going. I'm open to other ideas as well.
