Question about 2009 Hummer H3

Open Question

Hello! I have monsoon amplified system in my Hummer H3. After I replaced stock head unit using PAC C2R-GM24, monsoon subwoofer failed to work. All other speakers work well. I connected 4 RCAs of the PAC to 4 RCAs of the aftermarket radio. Is there any additional input for subwoofer or this issue has another origin?

You have to test them, either should work fine (as in use either pair) if that doesn't work connect one pair at a time and listen for the difference, one pair might be for factory midrange and other for tweeter.. there are two different wiring configurations...

SOURCE: 2006 H3 Hummer AC/Heater Fan Motor

I brought my 2006 H3 in to the dealer for the same thing. My blower stopped working all together but it started as an intermittent problem. He said he had to replaced a diode or resistor either behind the switch on the dash that controls the fan or on the fan motor itself. Have not had a problem since but that was only about 4 months ago.

SOURCE: 2006 Hummer H3 fails to start periodically

If you look in the owner's manual it will explain this. Happened to me a bunch of times, really embarassing. It is an additional anti-theft device . If the computer senses that the key is inserted improperly, or that it is not a perfect match for the code it has in its memory for your key, it shuts of the gas supply to your engine for approx. 10 minutes to defer theft. Still happens to me intermittently. Now only very rarely. Total pain. I cleaned my key..carefully, with WD40 and after drying put just a touch of graphite on the key and started the beast a number of times. My dealer didn't read the manual either. You must wait the full ten minutes before trying to restart....otherwise it never totally resets and (the first time this happened to me) you can sit there and fight it forever.

I don't have my owner'smanual handy to refer you directly to the proper pages, but its in there under theft deterent. Hope this helps......and that Hummer can provide aneasy fix for this.

I have a 2004 Hyundai Santa Fe with a Monsoon sound system. I reinstalled the stock head unit and with it powers on, it's locked? How do I unlock the Monsoon Stereo head unit?


Look in user manual or on back of head unit for unlock code. If not written down. You will have to contact the dealer and provide serial code from back of radio. It's a anti theft protection.

Why is there water in the spark plug housing unit for a hummer h3


possible water from rain/splash or a crack in the head at the spark plug hole. Dry out the area and run to see if the water is coming from the engine head or not.

Hummer radio wont work


If you have swapped out your old factory radio with another factory radio from a different unit, it will not work. It is coded to the VIN#, Just to replace a radio at the dealer you must link up and download the current configuration from the old unit using the GM TECH-II, then remove the old unit and install the new one, upload the old config files to the new unit and hope it works. Sometimes it doesn't and you have to keep swapping units back and forth to download and upload and eventually maybe getting a successful upload. If all your doing is replacing the factory unit with another factory unit, it will work if you take it to a dealer and they do the process explained above. Just don't throw out your old radio, they will need it because all of your old config files are still in it!
I hope this info helps!~subyguru~

Do you a any service lights on Many of the 2008's with the 3.7 were built with bad valve seats . Mine had the same problem and failed and GM had to replace the heads under warranty. Get there before it runs out,it costs almost 3000.00 if not under warranty

I have purchased a stock replacment radio for my H3 on ebay. How do i retreive the unlock codes once i install the radio with out having to pay a dealer $100 for 15munites of work?


Make friends with a Hummer tech, you're only other option. Unlock codes vary with serial number ranges so you'd never know without access to the database. Would be easier (and cheaper) of it was an aftermarket unit.
