Question about 1990 Ford Bronco

1 Answer

1990 Full size bronco, changed out ignition switch on colum

When i changed out the ignition switch on colum the plug was a little melted. why is the plug melted? sometime the truck will start and run for awhile then die, and not start again unless i losen the bolts on the ignition swith and reajust it. the truck ran fine before i changed the switch except for the turn signal and blower moter would not always work unless you wiggled the key ignition. so today i droped the steering colum and found that the starter ignition switch on the colum was popping in two pieces, the plastic plug housing was seperating from its metel housing. and the plug itself was a little melted but the conections looked good. so temperarely i put a zip tie around it to hold it good and tight while i went to the parts store, i had no more problums withe the turn signals or blower moter anymore, but on the way home the truck shut off and would not fire back up, it would turn over but not start. so i reached under the dash and cut off the zip tie and wiggeld the igniting stated switch and continued home, however i had to continue this procedure over and over on the ride home. then i put the new ignition switch in and the truck either wont start or it will run for awhile and die again, and then not start again unless i losen the bolts and slide idt back and forth on the colum. can u tell me what the problums is? and why would the plug be a little melted? all the rest of the wires look good

How do you remove an ignition switch from a ford bronco, 1986, full size

I would check to see if there is a little hole in the tumble next to the key. If so then turn the ignition to accessory and put a paper clip or something that will fit in the hole. Push the pin into the hole and the tumble should move a little more and then just pull it out.

How do you remove ignition switch on 1989 Ford bronco.

easiest way is to remove fuse panel cover, there are 2 9/16 bolts that hold the sterring coloum to the dash, remove them. coloum will drop down and allow easy access to the ignition switch. disconnect wire plug ( already having the battery disconnected of course) remove 2 nuts that secure it on to the colum and do reversal for install.

Bronco uses a RELAY switch under the hood. Is that what you replaced?

Swap it with the A/C RELAY switch (they are the same) to check it.

You will have to replace the connector, the contacts have been overheated and you will have more problems, if you can't get a repair connector from Ford try getting a good used one, all Ford models used the hardshell section, you may have to move around wires and splice in any new connectors needed. Before you start make a simple diagram of where the wires go.

1991 Ford Bronco with 5.0 and automatic. no power suspect main fuse but can't locate. battery good.

The main fuse block on a 1990 full size bronco will either be under the dash/steering wheel column, bolted to the firewall or under the hood on the passenger side of the vehicle on the firewall. I would also look at the ignition switch.
