Dear Professionals ,

How to disable , deactivate or remove the Panic Alarm from the H3 Hummer

because i don't know and when opening the Fuses Box i found the Horn + Alarm in one fuse

 

its wired into the bcm. the door jamb switches activate it. take a t15 driver and remove all 5 door jamb switches, unplug the connectors and tuck them in the holes(not too far so you can get them back out). close all the doors and activate the alarm.

1- no false activation= defective door jamb switch (you will have to plug them in 1 at a time and retry, to find the defective switch)

2- yes false activation= need to check further

thaaaaaaaaaaaaaanks i'll give the instruction to workshop so they can deactivate it

 

Only for a factory installed system, aftermarket installers will wire the unit in, most anywhere... You have to poke around under the dash for non factory: wiring, connectors, relays, boxes, etc.... GL

 

please how much does it cost to change the bcm ?

 

Why do you want to change the BCM??

Just follow the advice given and be done with it.

Just check the door switches and remotes and all will be fixed.

Why start another thread on the same topic as the other one you started

 

Because obviously the other posts is for the hummer novice and this one is strictly for professionals

 

Hummer Professionals? This isn't the link to the Craigslist ad???

 

hey i just posted the first one to find out the reason of the problem and that one just to get rid of it

and thanks to you all for your kind support for a newbie hummer user

 

So have you done the basic checks and fixed the problem???

Or are you going tear out every other part of the Hummer instead??
