I've installed a HomeLink transmitter in my truck.
HomeLink, for those who don't now, is a technology that is basically a garage door openers that is built into your car—no separate transmitter. It's really a pretty simple concept and I find it amazing that its only now been becoming popular within the last five years or so.
Many cars nowadays have HomeLink built in, but back in 1998 when my Silverado was built, it wasn't even an option. Instead, the overhead console (which was an option itself) had a compartment that opened up. You could velcro your garage door opener transmitter into the compartment and, when it was closed, a button in the compartment could be pushed, which would then push the transmitter button in the compartment.
When I purchased the truck, there were some parts missing from the compartment in the overhead console that allowed this system to work. The button could be pushed, but inside the console, the part was missing that would actually push the transmitter button. I never found that part in my searches, except from a dealer (and they wanted an outrageous amount of money for the part). So, instead, I kept the transmitter in the compartment, but opened the compartment to actually push the button myself.
This worked for a while, but earlier this year, the compartment door finally broke. So, I took the door off so I would still have access to the transmitter, but of course this was pretty ugly.
I began searching for a new door on eBay. Unfortunately, I never found just the door by itself. All I found were complete consoles, which I didn't need. I had a good condition console; I just needed a new door.
Even though I didn't find what I was looking for, I found something better. It turns out that even though GM didn't offer HomeLink in the '98 (or earlier) Silverados, they DID offer them in later model year Suburbans, Tahoes and Blazers (and their GMC corporate cousins). It also turns out that from around 1999 until 2002 (or thereabouts), the overhead consoles on those models were the same found in my Silverado. Therefore, the HomeLink module in those later models (which replaced the transmitter compartment I've described above), would fit perfectly in my Silverado's console.
So, while I was looking for a door on eBay, I instead found a HomeLink transmitter module from a 2001 GMC Jimmy. It was the same color as my overhead console and the asking price was reasonable. A few bids later and a few days for shipping and it was in my hands.
Here is a picture of it installed in the truck's overhead console:
It looks great and works great! I had a bit of trouble with the wiring (my own fault, really), but once I figured that out, I am very pleased with the result.
Now, some may ask, "What's the big deal? What's wrong with just having a separate transmitter?" Those people have a valid point. But, this was a cheap and modification that I could make to the truck with little risk of messing anything up. Plus, it is a solution to two problems in one: I don't need to find a new door and I don't need to find the part that pushes the button behind that door. I have it all built in now.
And, it just gives me some more buttons to play with, and that's always a good thing.
