90 V10 - Electrical gremlin rears its Ugly head.

[JCurtis]

While following my son the other day to bring his blazer home. I noticed that not only did he have a rear brake light out, but when he used his turn signals, not only did the blinker flash, but so did the back up lights...sort of like the wig wag headlights on a cop car.

I'm thinking its a switch problem... question is which one... turn signal, neutral safety, or stop light???

I'm open to some advice.

Start with easy and free stuff first.

Check all the grounds at each light location, check or replace the body to frame ground wires.

I would guess that living in Connecticut, your climate is rough on sheet metal and electrical connections.

Yep.. My brake lights wig-wag'd.
Turned out to be a bad ground terminal, at the bulb.

Same here....bad grounds.
