I have a 1999 coupe with 19,500 miles. Last week I was driving and using the page button to change my HUD from the gas gauge to temp gauge to oil pressure. It changed but then the gauge side went blank. The page button doesn't do anything. All I have is MPH and RPMs. The slide switch for dim and bright works and the up and down arrows work. When I start the engine everything on the HUD works for about 3seconds, like it should. Does anybody know anything about how to fix this? How do I get to dash out to check the connectors on the HUD?

Thanks in advance

 

I can't recall excatly but I think if you hold the page button down for a while it will change the screen layout. It's in the owners manual.

 

Hold down the page button for several seconds to change what is displayed. Tap it to change display withing that setting. You probably just held it a little longer than usual to erase the gauge settings. If you hold it again, you'll probably only get the mph or rpm and nothing else. Keep going till you get what you want.

 

wow this should be on the "thing you don't know about your c5" list! I am going to try it

 

It is: It's also in the owner's manual:

C5 Corvette Secrets:


-That you can put your key in the driver's door and turn it twice towards the front to unlock the passenger door and a third time to pop the trunk.

-That you can pop the trunk and also pop the gas cap cover by pulling on metal lines hidden in the back.

-The little slotted cover on the dash behind the steering wheel is where the inside air temperature sensor is located.

-All of the option codes are in the glove box.

-Tire inflation recommended pressures are on the driver's door

-The thing that looks like a little LED near the DIC buttons is a light sensor

-The thing that looks like a little LED near the defroster vent is a UV sensor for determining A/C usage to compensate for the heating effect of the sun

-The build sheet is in the front re-bar

-If you leave your turn signal on, in about 1 minute it will start to ding (loud enough to hear over the stereo) to let you know you have old timers disease.

-You can reset the oil life by pumping the gas pedal 3 times (but not with the engine running)

-Hold down the reset button while on one of the trip odometers and it changes that reading to the miles you've traveled since last starting the engine.

-Hold down the Active Handling button for 5 sec. to engage "Competitive Driving" on cars equipped with active handling (2000 and previous years must be stopped.)

-If you pull the seatbelts all the way out while you're buckled in, they ratchet back in to hold you tighter into the seat.

-Simply remove fuse #2 under the hood and your DRLs will be out permanently. Only thing affected is that when you unlock at night using the key fob your front turn signal lights and back up lights will not flash. Your front turn signals will operate normally, however.

-The side-view mirrors can twist both forward and backward, decreasing the chance of damage if struck.

-There is a release opening with a flap to let air out of the car when the hatch is closed. It is located just above the driver side rear compartment, behind the carpet and on the side of the car. Not that it really works well.

-Also you can ground your amp to a screw/bolt that holds the rear middle compartment to the frame.

-If you have a 6-speed car you can pop the trunk when the car is running by lifting the e-brake.

-There is a spot on the driver side just out of the middle compartment under the carpet for the lug nut key. You should have a compartment on the drivers & passenger’s side (in the trunk) and a center compartment. On the left (drivers) side of the center compartment, on the left side where the center cover fits, there is an 'indent' that holds the wheel lock key.

-If you turn on the headlights, then go to parking light position, the lamps remain up but the headlights are not left on.

-If you have the passive entry feature: If you lock your keys in the car, wait a few minutes and then shake the car. That will unlock the car.

-HUD has a shift light for manuals.

-Hold the PAGE button down and it’ll show MPH, hold it down again and it’ll show RPM’s, hold it down again and it’ll show MPH and RPM, hold it down again and it’ll show MPH, RPM, Gas/Oil Pressure or temperature.

-You can easily shift the M6 trans up or down without the clutch if you match revs. (Not great for longevity, however.)

-You can eject the cd from the in-dash player without turning on any power. Don't even need key in the ignition.

- You can pull the turn signal lever towards you (away from the window) to allow your lights to ‘flash’ which in turn notifies others in front of you that you are going to pass (must have the fog lamp option for this to work).

-The cruise will disengage if you purposely make sharp side to side turns while cruising at say 60-80 mph.

-When the engine is shut off, you can get the odometer reading by turning on the parking lights.

-You can program setting #3 (both memory buttons at once) in the seat memory to run the seat back and steering wheel forward for getting in/out of the car with the engine running.

- If you hate DRL’s you can pull the e-brake ONE click and they go off, or pull the #2 fuse.

 

Thanks everybody
It's working. I guess I should read the book or just drive it more.

 

I thought the HUD was going out on my 99 coupe, it kept messing up, only working sometimes, ect. I ended up needing a new battery and when I changed it I noticed that the problems I was having with the HUD and some other minor electronic ghosts seemed to go away....
