whats up guys i came across your site on the net and must say i thank God i did. im having some issues as the title says.. i own a 86 k10 and i was taking out the dash cluster and started checking the main plug that goes in the back of dash with a light tester and by pure accident touched two leads and blew somethimg cause my dash lights dont work or my heater. the heater wont turn on or make a noise. ive tested every fuse in the box and still nothing! i printed out a diagram and have tried to follow the wires to see but no luck yet. could it be a blown relay or blower resistor? does any one here know what it could be? thanks alot fellas
I looked through my wiring diagram and found a brown wire that runs from the fuse box splits and runs to the gauge cluster and the heater. If you have power at the heater and dash light fuses, this wire might be the issue.
