Question about 1987 Ford Bronco

1 Answer

I have a 1987 fullsize bronco. Recently I was driving and turned the heater on and as soon as i did the truck died. I have tried everything and all i can seem to figure out is that the 12v+ going into the ignition switch (above the column) is not getting any power. i just need to know if there is a relay for that and if so where, if not what else could it be?

Their is no relay for the ignition switch supply ,it comes direct from the power distribution box under the bonnet so either a big fuse blew as the heater motor was drawing too much current or it shorted out or the fuse connections are corroded and the heater motor was just too much for the conection

I have a 1988 fullsize bronco and one day it wouldn't start

down under the dash on the side of the steering column you will see a ingition switch they go bad,remove the two wire harness they only go back in onw way so dont worry,take the two small screws out remove the rod and take off and put the new one back.align the rod into the new switch place it on the column as if it were hooked up.turn the key at the same time you hold the switch in place and start the truck. after you get it adjusted then put it on and tighten the switch.

Oil presure issues

It is located on the bottom of the motor inside the low side of the oil pan. (pan has to be removed to gain access). And to remove the pan you may have to remove the exhaust. It's gonna be a project.

Good Luck

Hope this helps
