 Places to look for bad ground or bad connection.
I had an car once that would loss the gas gage and other things also.
I took the instrment panel out looking for a bad wire. I found it. It was
on the back of the instrument panel which was a printed circuit board.
Over time the connection had heated up and would loss contact.
I solved the problem by drilling a small hole in the printed circuit and
adding a small bolt & nut to retain the wire to the circuit and adding
a new wire connector to the wire. That did the trick. No more electrical problems with it. If you decide to replace the ignition switch, once you
drill out the heads of the bolts, the switch will come off and you can
screw out the remaining part of the bolts with pliers. You will need
to purchase new bolts of the correct size and length. I believe they
were metric on my Ranger. I agree with the other guys now, sounds
like the loss of a ground somewhere in the dash. Let us know what
what you did, when you solve the problem. |
