So my buddy helped me change my thermostat last night, because of my heating issues. The thermostat did the trick. But now my abs, traction, and Brake light is on... I checked all the fuses in the fuse engine bay fuse box and everything seems good.. I searched also to no avail... I didnt touch the speed sensors on the car at all...

Any ideas?

 

Something is either unplugged or a ground is not connected. Double check everything you pulled out to change the t-stat. Hard to diag with no codes.

 

Did you replace your tstat because your car was running too hot ? Or not heating up much at all ?

 

Yea it was overheating and the fan kept coming on. It was the thermostat. now all these light are on, im going to try the fuse box again.

 

How high was your temp getting? I ask because my fan is on after the car idles for only a few seconds once i stop driving. But my temp never goes past 208ish to 210 max. ( 97 degress Celsius.)

 

My temps would get to about 216 at times, freaked me out i knew something was up.

Anyway, So this weekend i checked all the connections and disconnected the fuse box again and didnt find anything, this is a little frustrating.

 

Did u drive through water recently or did it rain? Or slushy snow, cause that trips the abs sensor light cause the wires get wet. Great Gm engineering. If that's the issue, take off the wheels, unplug the sensor, and silicon the wire harness where wires go into plug, that fixed that problem for me

 

That isn't anything to be concerned with really. I've seen mine get up higher than that on a hot July summer day. So long as it comes back down after driving a few mins its fine.

 

No we literally Dissconnected the battery, changed the thermostat and when we hooked everything back up the lights were on... But now that i think about it, maybe some the coolant ran down into the abs sensor?


And as for the overheating thing, it would get up to 216 and the fan would come on, and it would stay there or go up a degree or too, then i blasted the heat to get it back down.. the thermostat was the issue, it barley touches 205 now.

 

Oh okay. I see. Yeah that would make me wonder too. Mine pretty much stayed at 190.

 

Anybody have any ideas on this? Its really annoying i cant go into Comp Mode or anything.

 

Sensors may need recalibrating..

 

Figured it out, We took everything apart again, and found a wire that was mangled behind the fuse box, Repaired that a bam everything works.
