A month ago when I traveled to a hot (90-100°F or 32-37°C) area and again this weekend (100°F or 37°C) I had the following problem.
When trying to start in the hot weather everything works ‘as normal’ until I go from ignition on to start and then no ‘ignition position power’ but the starter turns over as normal.
So as I am turning the switch from ‘ignition on’ to ‘start’ all the normal warning lights that are ‘on’ in the instrument panel go ‘out’ but the starter turns.
In troubleshooting I pulled the plastic cover off the steering column and when this no power situation happens, if I rap on the end of the ignition switch were the wiring are attached (opposite the key) with the handle of a screwdriver it will start.
Now of course the simple (well relatively) solution is to replace the ignition switch. But between the issue of the ignition and doors getting keyed alike again and having to drill out the shear-head bolt, I though I’d ask if someone else has had this problem.
Is there perhaps some dielectric grease normally in the ignition switch that could be melting at this higher temperature and causing a problem? Or something else ‘heat related’ in the switch ?
When I’m back in <80°F (<26°C) temperature the ignition switch works as normal, no problems.
Any thoughts or should I just order a new switch and rekey the doors ?
