DRY FIRST.
If you’ve made the choice to attempt to save you vehicle…DO NOT RUN OR OPERATE ANYTHING !
untill after you disassemble and DRY .
Far too many electronics will zap instantly if you try to operate anything.
– Most computer modules , fuse boxes, radios, amps, etc can be opened up…circuit boards removed-cleaned-and dried BEFORE energizing.
– un-plug and dry every connection, plug, and junction.
– take out the seats, take apart the upholstery, take out the carpets and pads, take off every interior trim panel…etc.etc.etc.
Completely dis-assemble the entire car like a model kit or restoration job…because you are restoring it.
dry
re-lube or pant as needed.
re-assemble
HOPE that it all works.
I’ve dis-assembled - dried - and re-assembled many electronics like phones, ipods, computers and toys, and the ones that were NOT powered up while wet DID work again despite having been through the washer or dropped in the toilet or spilled upon.
But some things have a hot memory circuit and fry upon getting wet.
