WHT Z06: Assorted Hacks

Here is a list of hacks I've done to my Z06. Many involve OEM parts.

Hack Description
Fob Fob Panic Button Disable
Reverse Solenoid Replace the reverse lockout solenoid
US Flag Aluminum US Flag
Weatherstrip Lubricant GM weatherstrip lubricant
XM Band Deletion Remove the XM band from the radio

Fob Panic Button Disable

The panic button the key fob can be annoying when your keys or whatever set off the alarm. Eventually I got fed up and put a piece of tape over the contacts for the panic button:


Reverse Lockout Solenoid

I started noticing that reverse was sometimes available while driving down the road. This was because my reverse lockout solenoid was failing. I replaced it with the car jackstands. It was not an easy process.

Original Replacement

The original was much larger than the replacement (GM 19178634). Ultimately I found it easier to remove the entire assembly and replace the solenoid on the bench. I later tested the original solenod with a suitable 12V power supply; I found that it frequently would stick in the retracted position.

US Flag

I'm not really big on putting decals or bumper stickers on my vehicles but I like displaying the US flag. I got this aluminum flag from ebay.

Weatherstrip Lubricant

GM Weatherstrip Lubricant (GM 3634770, also known as Krytox) is a silicone-free grease used for dressing weatherstriping. It works great but is expensive.


It's listed in TSB (#99-08-64-016A) as being one of the two products that should be periodically applied to weatherstrip surfaces. A cheaper option is dielectric silicone grease (GM 12345579 or equivalent).

XM Band Deletion

Some folks who do not subscribe to XM don't like seeing the XM1/XM2 bands displayed on the base or navigation radio. This is just a matter of unplugging the module which is located behind the carpet above the left rear wheel well or on convertibles between the seats and under the waterfall behind the center console.

[Navigation without XM bands]

When the radio does not receive any frames on the J1850 bus from the XM module it will remove the soft button for XM bands.
