Weird Electrical Problem(ac,wiper,radio)

[MikeU]

My ac, wipers and radio will not work sometimes on my 88 XJ 4.0. It has to be somewhere they are connected together. Sometimes it will work and then you turn off the car and turn it back on and it will not work for the rest of the day. I really need help on this.
I have been looking at the electrical diagrams but have not found the problem yet.
Thanks,
Mike

They're all on the same segment of the ignition switch :cool:

When it does this, try the horn too.

They're all on the brown wire(s) from the switch to the fuse block (and horn relay). Try wiggling the key switch when it happens, then wiggling the wire, etc, on down.

and if its the ignition switch an you need a replaceo- make sure you get the right one- manual and auto will not interchange. Their cheap, $9 or so. They all wear out.... you might want to check and see if the actual switch is loose and in need of adjustmant first-- lower column, right side, above your foot. If its loose, hollar.

Thanks everyone. The problem was the ignition switch. The switch was bad and also the connector on the brown wire was burned. I replaced the switch and the connector for the brown wire. Hopfully this will never occur again on this car but I have another so it probably needs to be checked.
