Do the lights come on steady or do they flicker.

My WTS light would flash on-off-on-off sometimes and I found the connector to the air temp sensor was flaky. I tightened it a bit and no more problem. As for the WTS light IDK.

There is a circuit that turns the lights on when you hit the starter which may be shorting out. If the line is shorted to ground it will turn on the lights in the message center and the brake warning light to test the bulbs. I posted the ignition circuit in the thread "Blower motor shutting off" which shows it for a 92 model.

My guess is that you definitely have an intermittent short to ground. Those can be hard to find. Look for a portion of the wiring that's chafing against a sharp edge of sheet metal.

I'm not saying it's a bad ground. I'm saying it's a short circuit to ground of the test line from the ignition switch. It's a remote possibility though. As far as heat goes, another remote possibility could be the plastic insulation of the wire could allow the short more readily when hot.

Intermittent connections or shorts are a beast to find. One technique is to wiggle wires around and see if that has an effect. Also the copyrighted Dodge fist thump on the dashboard.

The fact that it happens to both lights at the same time points to the common problem of the test line. If it isn't happening EXACTLY the same to both lights then forget about the test line as a cause.

Maybe the circuit is grounding when the brakes are applied, through the brake light circuit. Just a guess
