Black Plastic Restored

For longer than I’d like to admit, I’ve been trying to find a solution to the aged plastic trim on my H3 Hummer. The Trim on the vehicle has taken quite the beating from the sun, weather, and years of driving. This damage has left the plastic with this blotchy grey-ish chalk white color. I’ve tried a bunch of products that claim to restore the look, like Mothers Back-to-Black Trim and Plastic Restorer, but they barely last a few days. I can’t bring myself to use Plasti Dip or Bed Liner because it looks half-ass. The heat gun trick didn’tContinue Reading

CB Radio

The Citizen Band Radio, or CB Radio, is one of the most important parts to equip a 4×4 vehicle with. A CB Radio is a requirement for most organized Off-Road events. Despite it’s old design, the CB Radio is a very effective tool at keeping everyone safe on the trail. In an age of cell phones, Facebook Messenger, and a hundred other things you’d think that the CB Radio would be a thing of the past, but honestly it’s just as relevant as ever. What makes the CB radio a valuable tool for communication on the 4×4 trails is theContinue Reading

H3 Upgraded Battery

Next time the battery in a H3 Hummer dies, I recommend getting the Optima Battery 8042-218 D75/25 Red Top or Yellow Top instead of a factory replacement. Although, the¬†Optima D75/25 is much bigger than the factory battery and will not fit inside that plastic box… but who cares. Personally, I think the plastic box is just there to add a distraction from the small battery and the non-GM labeling of the battery. So I ditched that factory hummer plastic box that the battery was hiding in side of, and dropped in a much bigger battery in it’s place.¬† Reason being,Continue Reading

Leaky Sunroof

A few months ago I fixed an issue where the sunroof on my H3 Hummer wouldn’t properly drain the water. Which would make for a surprise after a particularly heavy rain fall. The problem was from going off-road with the Hummer and flinging mud and debris every where with the sunroof wide open. By design, all sun roofs leak which is why they have tubes to drain the water. If the mud and debris is forgotten about and never cleaned out, it tends to get jammed in the tubes. Once the H3 Hummer sunroof tubes are clogged, the water hasContinue Reading

H3 Hummer PCM Programming

After some research using the internet on PCM’s and Tuning, I found out that I don’t have the latest tune / reflash from GM for my H3’s 2006 3.5 L (211 CID) L52 I5 cylinder engine. I was able to check my vehicle by using a simple OBDII sensor I have and cross referencing numbers using TIS website by entering the VIN number. I compared the tune number from my previous post P0455 & P0442 ECU Fault Log H3 Hummer where the Vehicle Calibration ID on my vehicle as 12606370. The tune 12606370‘s description mentions that it is for “NewContinue Reading

Burnt Out HVAC Instrument Panel Light Bulbs

About year ago in my dashboard a light bulb for controlling the vents went out on my H3 Hummer, making it difficult to see which setting I had the ventilation on. A few months later, I had two light bulbs that didn’t illuminate on my HVAC (Heating, Ventilation, and Air Conditioning) Control Panel which began to make choosing the setting on the instrument panel difficult at night. I called up GM about getting it fix but all they want to do is completely replace the GM Part No. 15840354 CONTROL, A/C Instrument Panel, or with the part ACDelco 15-73909 GMContinue Reading
