Honoring My Father by Saving His ’99 Pewter FRC – Need Diagnostic Advice/Support
The moment I first laid eyes on that FRC, I fell in love with it. Even back then, before I knew what made an FRC special, I knew there was something about it that hit me differently than a regular C5. The body lines, the stance, the profile, there’s just something about this car that still does something to me today that I can’t fully explain. And that Corsa exhaust… it sounds incredible.
My father was a famously frugal guy, which made it even better. He hadn’t even mentioned to his wife that morning that he planned on buying a Corvette. Needless to say, it was a complete shock to my little brother and me, but boy were we excited.
That car became a staple of my teenage years. I have endless memories in that FRC. I drove it so much while learning that I actually passed my driver’s test in that car—a manual 6-speed FRC, first try. I’ll never forget the look on the instructor’s face when she climbed into the passenger seat, she told me she didn’t know how she was going to get into a car so low to the ground, haha
My dad was the cool dad. He’d go to late-night causeway sports car meetups, and we may or may not have witnessed our fair share of “spirited driving”… in Mexico, of course. The Vette to us, was a life style. Not just a car
But more than anything, that Corvette was therapy for him. His favorite thing in the world was hopping in the Vette, cranking 90s rock, Nirvana, AC/DC, RHCP, along side his cocker spaniel for the ride, and heading to the beach to watch the sunset. Over the years, he’s easily clocked thousands of sunsets from behind the wheel of that car.
He took incredible care of his baby girl, and it shows nearly three decades later.
Now she sits in my garage, and every time I stare at her, the memories come flooding back.
I lost my dad 3 weeks ago, March of this year to a heart attack. He was far too young at only 61. I am 38. What I wouldn’t give for one more sunset ride with him.
Because of that, this car is no longer just a car to me, It’s a piece of him. It’s part of my bloodline, and it will never be sold. My duty now is to bring his FRC back to 100% and preserve the legacy of the man who made so many memories in it.
That’s why I’m reaching out to this community for help.
The issues are a bit tricky because my father had recently begun troubleshooting them but never got the chance to finish, so I’m not sure whether these are all related or separate issues. Nor do I fully know what troubleshooting he has performed there was a multimeter inside the car and the passenger door panels were removed. All of the panels are also removed around the steering column. I know these cars have security module issues, as I had the same issue with my 2004 Z06.
Below are some notes that I have taken from my observations and troubleshooting.
—
The biggest problem right now is the cluster of error messages on the DIC that alternate one after another:
- Service Traction System
- Service Vehicle Soon
- Service ABS
- Low Tire Pressure LF, RF, LR, RR
Gauge Issue
- Oil pressure gauge does not work
Strange Electrical Behavior
One random but possibly related issue: while driving, all gauges suddenly dropped to zero (except battery voltage), yet the car continued to drive perfectly fine. After a minute or two, everything came back to normal, but the error messages aforementioned continue to cycle.
Because the car still drives like an absolute bat out of hell, I have a hard time believing all of these warnings are legitimate failures. My gut says this points more toward a module issue, ground issue, BCM/EBTCM fault, cluster problem, or possible wiring short, but I honestly don’t know where the best place to start is.
Brake Light Issue
- The third brake light works normally
- The main four rear brake lights do NOT illuminate with pedal input
- Turn signals and hazards work normally
- If the battery is left connected, the running lights stay on continuously
That makes me think there may be a shared ground issue, multifunction switch issue, or wiring fault in the rear lighting circuits. I just don’t know where to start here either.
Rear Window Molding
Lastly, the rear window outer molding is starting to peel up, which I know is a common FRC/Z06 issue.
Ideally, I’d love to replace it with a brand-new OEM molding instead of regluing it, but I’ve had zero luck finding one anywhere.
The part numbers I’ve been hunting are:
- OEM GM 88948473
- OEM GM 10400804
I’ve searched just about the entire internet and have come up empty.
Does anyone here know the secret sauce for solving this molding issue the right way on an FRC?
Thank you all in advance for any advice, technical guidance, or even just helping me honor my father by bringing the love of his life back to its former glory. For what it’s worth, I find a sense of gratification by hopefully being able to repair these issues myself, rather than taking into a shop to repair and having someone else do it. I know this would make my old man smile from above
With all my gratitude,
-Jeremy.

And my condolences on the loss of your father.
Do yourself a favor, and buy a factory service manual for the car. If you truly want to know the car inside and out, that is the bible to follow. That way you don't have to have a connection to the internet to make a decision.
You indicate you will be doing the repairs yourself. Do you have the mechanical and electrical expertise/experience to troubleshoot? Do you have a DMM, test light, adequate tools, and have the ability to read schematics and interpret the service manual? If you find yourself challenged in these areas you are best to take your car to a trusted shop, or this will be a frustrating experience for you. If you are proficient in those areas, then you only need familiarize yourself with the platform, and the forum can fill in C5 specific information, problem areas, etc. Just remember that this is a C5 corvette forum, not a "learn how to work on cars forum".
Good luck with your journey.
I lost my Dad in a similar way at 67. Heart related, sudden, and left behind a garage full of cool cars that did not run.
Peace to your family.
