Brake lights work, then don't.

[Frankenvan]

Help. My brake lights work two or three times after turning the key to the on position, then stop working. If I turn the key off, then back on they work two or three times then stop again. Any ideas on likely suspects? Granted, I do have wiring gremlins but I'm hoping there is any easy fix so I can be operational for the bbq Tuesday and the Greenwwod car show. I don't want to be driving a little car with no brake lights. Any help would be mucho appreciadod. Thanks

Frank,
Jumper between the wires on your brake light switch. If the lights stay on then the switch is bad, very likely if it's the hydraulic type.

Thanks Don. I did that and the lights stayed on. I'll replace the switch.

Hydraulic?

Before you pull the old switch put a piece of Saran wrap under your master cylinder reservoir cap and replace the cap. No air in means less brake fluid out.

Don't let the fitting the switch screws into turn when replacing the switch or leaks will ensue. Been there.

Anyone have an extra brake switch they could sell me at the meeting tonight? I need the hydraulic type from the Mark I era. Thanks.

I've got one, see you tonight.
