When a dashboard acts up, show it who’s boss

Dear Tom and Ray:
Here’s the deal. As I’m driving my surveillance van down the road, on occasion my gauges will flatline. It happens every so often. Usually the next day they (the gauges) will perk back to life, or they may jump to life while I’m barrelling down the road after some knothead running from a repo. However, it should be noted that the warning lights continue to work during that time. What is odd, the ABS warning light will come on when the gauges flatline, and the ABS warning light will then turn off when the gauges return to life. It is a mystery. So, I came to the best car dicks I know to solve this caper.

TOM: We were working the late shift at the garage, Steve. And this doll walks in. She’s got a ‘99 Town and Country.

RAY:And guess what? She’s in a jam. Her dashboard takes a powder every so often. Just like yours.

TOM: My brother gets in, and sure enough, the instrument cluster has taken it on the heel and toe. Looks fried.

RAY: So I give it some serious chin music. I whack it with both fists on top of the dashboard, and, whadda ya know? It does a Lazarus – comes back to life. All lit up.

TOM:So I tell her that sometimes a bad connection on the instrument cluster’s printed circuit board can cause intermittent failure like that. Sometimes by whacking it, you can get it to come back to life temporarily, confirming that the problem is right there, in the cluster.

RAY: I tell her, even if you don’t get it to come back to life, giving it a hard shot in the beezer will make you feel a whole lot better. So I tell her, look, if it’s not the instrument cluster, it could be a bad body control module, which is a little computer that controls things like lights and interior functions. But in her case, I was pretty sure it was the instrument cluster.

TOM: So she asks how much cabbage we’re talking about.

RAY: Depends, I say. If you can find a cat willing to take out the cluster and look for cracked solder joints on the circuit board and solder ’em back together, it could be an hour’s work. But you might not find someone willing or able to do that.

TOM: Another option is to grab up a used one from a junk yard. But, of course, that one could be halfway to the big sleep itself. You never know.

RAY: If you want to replace it with a new cluster, that’ll definitely fix it, but you’re looking at big money. A bunch of C’s. South of a grand, but maybe not by much.

TOM: “That’s a lotta spinach,” she says. “I may have to put this thing in the wooden kimono, along with my deadbeat husband.”

RAY: We nodded. “Good luck, ma’am,” I said. We never saw the broad again. So we’ll say the same to you. Good luck, Steve.
