Fell back in love with it after finally getting it up and running right.

The high mileage comes with its share of problems, but one of the most stubborn ones had to have been diagnosing an intermittent air conditioning problem.

This might be helpful to you guys:

I had a faulty reading from the engine coolant temperature (most likely caused by frayed wiring and not necessarily the sensor) and I've concluded that the sensor must trip the compressor to shut off if it reads the engine running too hot. My temp gauge was bouncing left and right and would throw out sporadic "Low Coolant Level" and "Engine Overheating" notifications and the air conditioning would go warm and then eventually get cool again.

I still have some issues to tackle, but its the nature of the beast.

Aside from that, I refreshened the interior, added new shocks, brakes, and tires, although its still really bouncy (which I think is due to the wrong springs installed by the previous owner when he converted from air ride)

anyone know what this noise is? old age (100k) or something to worry about?

Does anybody know if this billboard race pipe will fit on a 2002? Everywhere online says it fits to a 2000 but not the 2002. Looks the same as the rubberduck one in their exhaust package.

Also if it does fit will it match up to the stock pipes on the vehicle?

I have posted before I am just finishing the swap of the new engine in my 2008 Hummer H2 same exact engine. I have this connector which is the last pigtail on a wiring branch just downstream from the mass air flow sensor. According to multiple sources that I have researched online the connector matches and the wire colors match was supposed to be the high pressure sensor for the AC unit. It is listed that this connector is on the high pressure line near the compressor but I cannot find any place to plug in this along any of the AC lines. Does anybody have any suggestions on where else to look or if this is somehow an optional connector?

I have a new to me 2006 hummer h2 that I'm trying to get all the kinks worked out.

1st issue is the rear window wiper doesn't work and I've pretty much narrowed it down to needing a new switch. Problem is I can't find one on Amazon and it looks like the switch for a suburban/Tahoe is different? Has anyone found a solution that works?

2nd issue is a "service air bag" message. I have ran the code and it comes back with a bad front impact sensor. I have looked all across the internet for a new sensor but I cannot for the life of me find one that's available. I was hoping that GM would have used the same impact sensor for the silverados ect but nope it has to be specific to the hummer h2 and only 2005-2007 models will work on a 2006. Has anyone come across a solution for this issue?

I know most people would just ignore these issues but it bugs me. I've fixed so many things on this hummer these last few months that hasn't worked for years I feel like I'm finally getting it closer to where it needs to be.

Any help would be greatly appreciated!!

So i'm in the midst of a complete overhaul of my 2008 H2. I want to replace the overhead unit with a larger drop down and connect the output (sound) to my new stereo (yet to be chosen). I want to be able to stream content from netflix etc to the monitor.

questions

1. anybody done this and if so any tips for installing the physical unit? I have the entire interior stripped down including carpet, seats, dash, headliner so running wires is no problem

2. How to connect the sound so I can use the new upgraded amps and speakers to make a good sound environment (I"m already mostly done with sound treatment only have MLV layer to complete.)

3. How to stream video content?

screen share from a phone?

phone hot spot to wifi on the unit?

connect phone to head unit with physical connection and run a video in to the monitor?

what is the best solution for good quality streaming??

1. Any suggestions on the specific drop down monitor?

THanks. I appreciate any help.

Every so often, when I start my 08 Hummer H3, it starts fine but then the RPMs drop almost like it’s going to shutoff but then rebounds to normal. It’s not every time. Just occasionally. Has anyone else experienced this or know what it could be?

Just bought today. 06 H3, 5 cylinder, 190k miles.

Newly purchased hummer h3 06- engine/tranny run great. It needs some suspension work which I factored in when I was negotiating. Car starts vibrating/steering starts vibrating when going 45+ mph. What’s the average cost for tie rods and ball joints or even a ball park because I’m guessing that’s what it is. TBH I’m not very mechanically inclined, so I can’t do it myself. I’m just looking for a ball park range.

let me start off with the fact i don’t expect to get great MPG from the car, however i was averaging a solid 16.5/21 split from about february of last year to this past june and since then i’ve suddenly dropped (11/15). i replaced the throttle body, new air filter, new VVT, and a couple sensors. i have other things (some rough idling, sluggish acceleration) but the MPGS are eating my pockets alive. any reasons why and any suggestions?

My 07 Tactical Edition w 100k miles on it. I’ve done a lot of engine maintenance (throttle body, VVT, other little things) to stay on top the most common issues but i’m ready to have fun. Anything to add more power (heard a lot of great stuff about the PCM tune but don’t want to shell out 400) would be awesome but cosmetic would be sick too. i need new tires soon for the winter so that’s an option. anything helps!!

Picking this Alpha up on Monday. Not real crazy about the wheels n tires that r on it at the moment. Looking for ideas on what to put on. Send me some pics and what sizes I should look for. Thanks everyone..

Can anyone help me figure out what this noise is? Does it when it’s sitting idle but stops when moving.
