Anyone have an idea on what is wrong:

Memory seat moving to full forward- not set that way
"Check gauges" message
Horn stuck on

Where is the horn so I can disconnect?


THANKS MUCH
Charlie

Sounds like a classic case of posession. :screwy: I would start with the battery and go from there checking all the fuses. Any codes? Good Luck! :cheers:

Under the front right side (passenger side) you will see a panel with louvers in it. Remove the plastic panel and you will see that the horn is held by one bolt. I think that you may need to remove the air spoiler but can't remember. Just more screws -- metric. Very simple to get too once you lift the vehicle safely and support it with jackstands. :D

Does the seat move upon entry or exit? You can push and hold both buttons for a 3rd position. :roll:

Wow! I'm 6'4" and with the seat all the way back, I can barely push the pedals all the way to the floor. Either you're really tall, or I've got stumpy legs!

I had a problem with the horn on my 98. The switch in the steering wheel was sticking On all on it's own. Usually, a good couple of whacks with my hand would get it unstuck, for a while. I ended up pulling the fuse. I ended up with a new steering wheel, the switch was not servicable. I can't tell you where the fuse is, but I can tell you that your Owners Manual has a complete listing of the fuses, with pictures to show you where they are.

I also had a problem with my 98's driver's seat control module. The seat would move on it's own sometimes. Had to be replaced. It's a big black plastic box attached to the bottom of the seat cushion.

These problems were not coincident, though. Your problems are. That would suggest the problem is something common to both the Horn and Seat. I have no idea what these two systems might share in common.

See what codes you have

The IPC display, the 20-character, vacuum florescent screen above the steering column that says "Corvette by Chevrolet" every time you turn on the key is a powerful device.
DIY Service Techs are going to be most interested in the LPG’s ability to show diagnostic trouble codes (DTC) for all the modules that transmit them..

The "diagnostic display" mode is entered with the following Procedure: Page 8-500

Turn on the ignition but don't start the engine.
Press the "reset" button to turn off any warning messages
Press and hold "options" and
While holding "options", press "fuel" four times within a 10-Second period.
Initially, the on-board diagnostics go into the "automatic" mode, which shows each module's DTCs in a pre-set sequence: (Page No. are for the GM Service Manual)

10 PCNI Powertrain Control Module page 6-357 - 6-361
28 TCS Traction Control system ABS on page 5-86
?? RTD Real Time damping page 3-136
40 BCM Body Control Module page 8-405 LTD Page 8-727
60 [PC instrument Pane! Cluster page 8-508
80 radio page 8-213
99 FIVAC Heater Vent-Air Conditioning page 1-118
A0 LDCM Left Door Control module page 8-904 to 8-951
Al RDCM Right Door Control Module page 8-904 to 8-951
AC SCM Seat Control module page 8-1064-8-1082
B0 RFA Remote Function Actuation page 8-676
For each module, all DTCs will be displayed. If none are present in a module, you will see "no more codes" on the ICP display. There are two kinds of DTCs, "Current" and "History," designated with a letter suffix, "C" or "H". A current code indicates that the malfunction is present in the system whose module is displaying data. A history code indicates a problem existed in that module sometime in the last 40 or 50 ignition cycles. When not accompanied by a current code of the same number, it is possible it's evidence of a previous problem. Now solved, that was not removed by clearing codes. More likely is that a history code indicates an intermittent malfunction.

"Intermittent" are the most challenging DTCs. An intermittent may have happened only once, may have happened more than once but is inconsistent in its appearance or may be happening on a regular basis but not at the time the IPC is displaying codes. History codes can also be caused by a current malfunction in a system that is not Operating at the time DTCs are displayed. An example is the rear window defogger, which doesn't operate until the BCM detects engine rpm. For history codes set by a system that does not operate with the key on and engine off, a special diagnostic tool called a "scan tester is necessary to properly diagnose the malfunction.

Once the IPC has displayed all 11 modules, the system goes into the manual mode, which allows selection of each module, using combinations of DIC buttons. The manual mode can also be entered at any time during the automatic sequence by pressing any button except "E/M". Once the IPC displays "manual diagnostics", you may select a particular module by pressing the options button to go forward or the "trip" button to go back. Once a system is selected and a DTC is displayed, if more than one are present; press "gages" To move forward or "fuel" to go back. To exit the diagnostic mode at any time, press E/M". If you want to erase or "clear" codes, press "reset". Clearing a code does not repair a problem. You are simply erasing the evidence of it in the module's memory.

Erasing DTC Codes -- 1 of 1

You can acess all of the cars trouble codes from the dic and erase them! Here is what you do: Press and hold options and then press Fuel 4 times while still holding the options button you must do this quickly. A message will appear saying "Diagonstics" then it will automatically read off the codes. Like....02-PCM(No codes)....03-BCM(No Codes)...ect. if there is a code it will look something like this 02-PCM (1052H) NOTICE THE H at the end of the code, That represents a code that has happened in HISTORY. If there is a C after the code it is CURRENT. To clear the codes let it automatically cycle through the codes then it will come to (MANUAL DIAGNOSTICS) this is where you can clear codes. Use the options button to scroll forward and the TRIP to scroll backward find the code(s) to be erased like 02-PCM (2Codes). To erase this, press and hold the reset button until it says "NO CODES" There you have done it!!!. To exit the Diagonstic menu press the METRIC BUTTON!!!

I just had the horn stuck experience myself. On my way home from the Arizona Route 66 Fun Run from Oatman AZ to Phoenix and it just started going off by itself. Just like RocketSled I could bang the horn pad and it would go off. I was afraid I would pull up behind a "*******" (if any of you are ******** out there don't take exception please) and he would get pissed off at my "random" horn blowing, so I decided to disable the horn for the balance of the trip. The manual told us the horn is on fuse #11 under the hood. Pulled it and drove home no problem. Will get the car to the dealer for a new wheel/switch this next week.
