Fix It Right! - Evaporator Core Replacement (S1E5) Demonstrated on a 2005 Jeep Grand Cherokee 3.7L V6 4WD.
In this video, we demonstrate the process of removing everything that covers the HVAC airbox on a 2005 Jeep Grand Cherokee, which essentially involves having to strip the dash down to the firewall.
Essentially, this video differs from our previous videos in that in this case we show a job that isn't really safe to attempt by most DIYers and should be taken to a professional, and we show why it's best left to the pros.
WARNING! Removing the entire dash of a vehicle is an intensive process that should not be attempted without extensive expertise and a comprehensive set of tols, including AC recovery equipment and specialized tooling as necessary. This process requires the disabling and disassembly of critical safety systems such as airbags. AC work often requires certification - in the United States, the Clean Air Act's section 609 mandates certification for working with automotive AC refrigerant. Since this is a task best left to professionals, only an overview of the process is shown without getting into specifics.
*** PROFESSIONALS ONLY *** This repair task may be difficult or dangerous to attempt. It should only be performed by professional technicians.
*** NOT DIY-FRIENDLY *** This task is best left to professionals.
*** CERTIFICATION REQUIRED *** This repair task requires certification in many municipalities. Check your local laws before attempting.
IMPORTANT NOTE: Please read the disclaimer text at the start of the video before attempting anything shown therein. Take your time, take care, and be safe!
About the "Fix It Right!" video series:
"Fix It Right!" is a series of how-to videos intended to give do-it-yourselfers basic instructions on proper vehicle repair and maintenance. All of our videos show real repairs being performed on real vehicles by real technicians in a real auto shop. (Repairs are filmed and shown with the permission of the vehicles' owners.) Although there may be more than one way to perform any particular repair (and in many cases there are lots of ways!) we try to focus on the methods that will be safest and most expedient for DIYers with limited access to tooling and equipment.
We will also occasionally be showing repair processes that are too complex or dangerous for DIY, or require specialized tooling, expertise, equipment, and/or certifications. Those episodes will highlight the importance of hiring a professional auto technician for tasks that are not DIY-friendly, and demonstrate why such tasks are best left to professionals.

NOTE: This is obviously not a how-to on auto repair, but fear not, more how-to videos are in the works!
The story so far...
We're One Source Automotive, a small auto repair shop based in Florida. We fix pretty much anything we can get repair data and parts for. We also produce a series of instructional videos for do-it-yourself auto repair, including when NOT to do it yourself.
We also like us some Minecraft - everyone that works here has their own personal Minecraft copy, and we occasionally get our SMP on when nothing's going on in the shop. (Sorry, the server's private!) In fact, we've been playing Minecraft since not long after Mojang started accepting "prepurchases" for the alpha.
A while back, one of our guys built the mother of all minecart tracks, a 125,000-block-long mostrosity that was dubbed the Minecraft Intercontinental Railway. At the time, it was arguably the longest verified-length single track ever videoed.
This was in the Beta 1.8.1 era of Minecraft, and now that the 1.0.0 release is out, he revisited the idea. Only this time he doubled the length to a quarter-million blocks. Yep, this time around the track is a mind-dulling 250 kilometers, or just over 155 miles, long.
Some facts on this video and the cart ride from whence it came:
- The video had to be recorded six times on two rather powerful computers in order to get enough usable footage, and even then there are sections that have TONS of visual glitches and unloaded chunks (especially the giant ocean biome about three-quarters of the way through). Apparently Minecraft 1.0.0 has some bugs regarding chunk loading when in a booster-track-propelled minecart over an ocean biome, and only under certain as-yet-undetermined conditions, as these anomalies don't occur when walking/running/flying down the track over the most affected areas, and other biomes don't seem to be affected. Mojang should probably look into the chunk code as apparently there's a problem somewhere.
- At the standard minecart speed (8m/s) it takes eight hours, forty minutes, and fifty seconds to ride from end to end. We've timelapsed it pretty severely in order to keep the video's running length under half an hour.
- Again at the standard minecart speed, it takes twenty-six Minecraft days to ride the track end-to-end. Almost a whole in-game month.
- This video was built from 350+GB of footage, and the only reason it was that small an amount was because we had to record it in widescreen 480p - if we did 720p we'd have burned over three terabytes of disk space just holding it.
- The map is only about forty chunks wide, but more than fifteen thousand chunks long. Basically Steve was moved from spawn to 0,0 and headed due "north" from there.
- The map is also almost two gigabytes in size, and when packed into a ZIP it's a 1.2GB archive. We're looking into hosting it somewhere, so watch for a channel comment if we find somewhere to put it for download.
- There are markers every 1,000 blocks (1 kilometer), in the form of glowstone on both sides of the track. Every 5Km there's a wider glowstone marker set, and an 'L'-shaped marker every 10Km.
- At the top speed, the video is approximating a travel speed of 256m/s, which translates to projectile speeds: ~900 KPH or ~570 MPH, or just under the speed of sound at sea level. Even at this speed it'd take over twenty minutes to make the run!
Tools used to build this monstrosity include:
- Minecraft 1.0.0, of course, in Survival mode. Don't have a copy yet? Why not? Whatcha waiting for? - Marglyph's TooManyItems mod, which was used to build/test the basic track sections. - simo_415's SinglePlayer Commands mod, which was used to rapidly build tunnels through the occasional mountain, as well as to teleport around, which is a pretty major thing when you're moving miles at a time. - sk89q's WorldEdit, which is what SPC uses to make magic happen in-game. - lahwran's ZanMiniMap, which gives that little overview at the top-right corner. - zombe's modpack, for powered flight without having to stay in Creative mode, as well as a plethora of other effects. - risugami's ModLoader, which is used to load other mods. - sp614x's Optifine for multi-processor support and extended chunk loading range - this is the only reason the over-ocean portions are as good as they are, as without Optifine the chunk loading never kept up with the normal cart speed. Unfortunately, Optifine caused some visual glitching on its own, most noticeably in snow and ice areas (e.g., frozen-tundra biomes).
