My Corvette is Posessed!
This is the second time this has happened.
93 6spd, No PKE, No auto AC, No power seats, Delco Radio...not Bose.
It only happens on long trips. I was cruising at 70mph with Cruise on...and all of a sudden the PKE light comes on the cluster and the doors lock, and the hatch pops open....at speed.
The previous time the doors locked and unlocked, the tape deck ejected the tape and the hatch popped.
After stopping and restarting the car...the light stayed on. I shut it down again for about 2 minutes while I changed underwear....and after restarting....the light was off.
Strange....since I dont have the PKE, or fobs, etc.
Any suggestions on what is going on??
Last time some bags got sucked out the back...and the wife was not to happy to get backinto the car...this time it just scared me, but not a good feeling at speed...!!

damn! That has to be unnerving!
I would suggest you check grounds... that's my first idea.
Inside the kick panels are main ground points. Make sure there isn't any corrosion on them.
Also, check the main grounds around the battery. It might require some disassembly of the body and inner fender to access this area completely. Also, check the main power leads behind the battery.
Finally, www.helminc.com and get a copy of the Factory Service Manual. It will have the appropriate flowcharts you will need to back track this problem.

I am going to play the devils advocate. Not saying you don’t know your own car, but how do you really know you don’t have PKE installed. I know for a fact that the PKE light is directly connected to the PKE receiver. There is hatch circuitry in it also. And it has been known that it can over and activate the doors and hatch at will. If you know what to look for you can see the PKE by removing the A/C control and looking behind it. Or remove the top pad (lots of work). I would tend to say if the light comes on, you probably have PKE.
As for the tape deck, I have no clue. You can pull the PKE fuse but might kill your radio also depending how its wired. That would shut down the PKE. It usually is a common fuse but I need to check on how it is labeled.
If you go into the PKE programming mode with the buttons on the gauges/fuel panel and the PKE light flashes, you have PKE.

I thought PKE was standard on '93s. It is common for the keyfobs to not stay with the car, so you may not be aware you have it - but it's there alright.
Accepting that the function is there, is it at all possible you've got a fob lost in the car somewhere by a previous owner. If it is lodged under / in one of the seats you could be 'accidentally' pushing a button unknowingly on those two occasions - or a third! Good luck with your problem,

You have a ground issue, You are blaming the PKE because the light came on. PKE has nothing incommon with the radio, except the ground. Start check the common grounds and work from there, I have seen other posts like yours. Do a search, that might help you.

I dont know for sure if I have the PKE or not....I need to verify this. Just assumed I did not since I dont have any fobs....
I will start tracking down my grounds and checking them.
Play devils advocate anytime...I am by know means a GURU...
If I determine that I do have PKE...do I just take it to a dealer and get some fobs....or can I get the code somewhere...etc etc?? Try to stay away from the stealership as much as possible!
Its time to start checking every crack and crevice for those dang fobs...its the only thing I think of that would trigger the hatch!

Just because you do not have any FOB's, does not mean the PKE is not there. The PKE is built into the car, the FOB's are just a piece of the puzzle. Trust me, you have the PKE!!

Are you the original owner of this car? What pops right into my head is that some overzealous car stereo or alarm installer hacked the PKE circuitry. If not that I hate to disagree with folks on the forum but YES there is a fuse that supplies power to the radio and the PKE module. If the PKE module is skitzing out and pulling so much current it would cause the radio to lose power and possibly eject the tape because the current has diminished to the point where the tape holding solenoid can not stay engadged. (whew long sentence)
It really sounds like the PKE module is wigging out. In agreement though it might be loose grounds.

Fuse # 40 (5A) supplies power to the PKE, radio control head and radio receiver box. PKE always needs power, radio needs it for memory and receiver for delayed bus. The line is always hot.
I like your theory on the eject problem, but in reality it is a stretch. I don't think you can pull the 12 volts down so low that the fuse would not blow first. The fuse only knows current and you will have 12 volts on the output side till it blows.
It would be a nice find to find the key FOB but unless your sitting on it.....Looking for a bad ground or anything strange with the after market setup is a valid starting point. I thought the PKE was standard also but was not sure and did not want to make the statement.
I have seen several posts where the door locks were going nuts, PKE was the suspected item. The PKE box can be unplugged but you will loose your power door locks. Charge on
