1981 chevy c10 control module

(1/2) > >>

kgross401:
Question what does the control module do or control?
I have a short some were in wiring could the control module be bad and causing the short?

bd:
Way too vague!  ANY power wire or appliance that passes current to ground inappropriately can be the cause of a short. 

Which control module are you questioning?  What makes you think there is a short?  Are fuses melting?  Which fuse(s)?  Describe the symptoms and when they occur.

JohnnyPopper:
Got smoke?  ;D

kgross401:
the control module which is under dash above gas pedal I unplugged it and everything still works.
The problem I'm having with fuse popping is labeled horn which is above the bat single pin when I plug fuse 20A in (horn slot) it pops as soon as i push it in.

Mike81K10:
You may have a short in the steering column horn wire. Disconnect the steering column wire connector and then you can check for a short to ground in the column. If OK, check the rest of the wires to the fuse!
