Hi Im David. disconnect both terminals on the battery, hold them together for 20 seconds. reconnect them. see if that resets everything.

Customer: replied 2 months ago.
I already tried discounting batter terminals few times but no change.
I pulled the horn fuse for the time being and tried cleaning connectors under passenger seat as well..

well the traction control and abs light are going to be related. if the abs light is on the trac light will always come with it. apparently you had to remove the dash and lower the steering column correct?

Customer: replied 2 months ago.
While removing dash, I didn't disconnect anything from driver side expect for steering shaft. I disconnected it from floor, just behind the brake pedal
Expert:  david craig replied 2 months ago.

check the brake switch bracket. do you have brake light?

Expert:  david craig replied 2 months ago.

pulling the dash out, even though not disconnecting anything pulls on the wires and harness. something is disconnected. did you have the battery disconnected while doing the work?

Customer: replied 2 months ago.
I did disconnect the battery before starting anything.
There is no brake light on dash. The e-brake light is working normal
Expert:  david craig replied 2 months ago.

do you have brake lights in the rear of the vehicle?

Customer: replied 2 months ago.
Double checked, I'll 3 backlights are working good
Expert:  david craig replied 2 months ago.

ok. well did you have any of these issues before replacing the heater core?

Customer: replied 2 months ago.
No, all these issues came after this repair
Expert:  david craig replied 2 months ago.

you will need to thoroughly inspect all of the connectors and wiring harness to see what became disconnected/broken. it may only be 1 connector that has all of those circuits going through it.

Expert:  david craig replied 2 months ago.

sorry, but there is no other advice to give you. something is disconnected.

Customer: replied 2 months ago.
Exactly which connectors you want me to check? And how can I access these?
Expert:  david craig replied 2 months ago.

there is no rhyme or reason as which connector you need to check. you may have to pull the dash again to do a visual
