New member here. Bought a cool car today with a couple problems. Hope I can get some ideas on how to fix them on here. Dash MPH and odometer don't work. All other gauges are fine. The lights are on so where is the MPH digital display? Brake light is on. I guess it's the emergency brake light? Horn clicks but has no sound. Door panels are dry rotted. Only 53,000 original miles. Leaks a little from top on drivers side. Awesome driving experience. Just need to work on it & get it right.

OK thanks.

Brake light = low brake fluid or emergency brake on- do you know how to operate it on a C4 - they are a little different? Speedo, post a picture, does it light up dark orange just with no numbers = polarizer film worn out, need to send to Batee.com ( need more info and pictures)

I am fairly confident from the picture your polarizer lens is bad on the center display. Do you have a pair of the old polarized sunglasses? Put them on and look at the display, can you see it at all? Also, the brake likely fluid or you haven’t released it properly

OK I’ll work on that next. Thanks for your help.

How’s the battery? Mine does that when the battery is weak. My car has a draw somewhere so even trickle charging it only last like one or 2 years. More recently I try do drive it once a week and that helps a lot.
even after changing the batter I drive it for like 20 miles and then it works fine after that because the new battery sat for a while and had to charge up. Try charging then driving the car for a long drive see what happens.

Lebl1540

That's a good idea. I just bought the car so I have no idea what kind of condition the batter is in. Thanks.

The '91 I just got does the exact same thing. From my research, the electrical connections to the cluster can get dirty or oxidized and cause this problem. I'll try the sunglasses trick first, but then I'm going to remove the cluster and clean the connections.

Welcome to the world of Corvette life, my recommendation to you, join a club, mostly owned a C4 one time or another, or know were to get help.

I would say, go to car show, but most of them are cancelled.

Welcome. Enjoy that car!

Clock-work

My '96 surprised me one cold day with a blank screen identical to yours. Drove it a few miles and it came back to life. Since then and at varying outdoor temperatures the display has randomly gone blank and when it does I can sometimes bring it back immediately by giving the top of the dash a firm hit with my hand. That's a clear indication of a lose or generally bad electrical connection. I will service it soon and check all connections for tarnish, corrosion or connections that have lost their tension. Correct as needed and add a little bit of Caig blue "PreservIT", P100L liquid to each connection point. Couldn't hurt.

The guy I bought it from said he can tap the dash and make it come back too. Let me know what you find. Thanks.

My 92 did that when I bought it. had connector on back of display, it's a common problem.
