Car alarm troubles

[ncff07]

Was wondering if anyone knows anything about car alarms? I have 2003 Chevy Blazer and have had it for over 5 years without any problems with the alarm. I think its an aftermarket alarm by how it acts. It will arm itself no matter if the lock button is used on the FOB or not if the doors are closed after about a minute and if the doors are open it will still arm itself after about 10 minutes. BUT I had walmart change my oil yesterday and I don't know what they did but the alarm has been deactivated completely. Plan on taking it back tomorrow but its a 20 minute drive and had rather fix it myself if I can. Now when the lock button is pressed it will lock the truck but not set the alarm. I've disconnecting the battery to try and reset it but that didn't work and the small red LED light stays on all the time now when it isn't running and before it would just flash. the only way I could get the alarm to go off was to press the lock button twice so I know it will still sound off but no idea what could have been done to deactivate it from working how it normally does. It doesn't chirp now at all and before it would chirp once to activate it and twice to deactivate it.

Might be the alarm module, I had an older vehicle with the similar alarm problem, that it will go off by itself for no reason. Turns out the back window was leaking water into the module in the quarter panel inside. Replaced it, and it works fine. You might want to get the module checked out.

Good luck.

That is a good idea never thought about that and the front door did leak a little until I put new hinge pins and bushings in.

Toasted alarm module what Calvin says. Try to take a module and sniff around, if burnt smell. Buy another module.

The average of aftermarket alarm module life is about 5 years. Many time I see the alarm modules installed inside the dash on the driver side. I hope your old module can replace with new module without cut wires. Just pull connectors from the module, ID model/serial number, google it to see where to get a new module. Good luck

I hate f---ing alarm devices, every time I pick up customer's vehicles for services, these vehicles chirp loud I can't hear, I put my hand on the hood or fender to make sure it's no alarm chirp. Waste my time. Some car howl low chirp sound as I feel nothing but my mechanic wave at me, sign alarm, like I say oh f--k, disable it by fob. Most bother me is aftermarket alarm systems that I'm not familiar with complicated fob or remote.

Why I like aftermarket alarm system over factory alarm system? Aftermarket alarm system is hard for theft to disable it. Also aftermarket have start-up engine button and alert your remote like 1,000 feet away when someone touch your vehicle. Customer should know better that if his car got aftermarket then go to local who installed aftermarket or bring the diagram to your place. I understand most mechanic like me hate aftermarket without diagram. You can't said NO to customer since you do not have the diagram. Save your time.

I had one before when I grew up from Chicago in the bad crime area.

I hope its something simple like just plugging a new module in. But what I cant figure out is why when I took it and parked it outside Walmart and set the alarm it worked fine but when I left it didn't. But I did some reading in the manual and it has a factory alarm too that isn't as touchy and uses the horn instead of a siren so if its gonna be a pain I'll just start using the factory alarm system. Never knew my truck had 2 alarms on it.

Same as what I received customer complaints over erratic alarm devices. One thing you can tell if module is working by read the red LED that will interpret you. If no red LED light, there is no power (blown fuse or open wire) in a module or remote unlock/lock doors to watch the red LED to see if there is normal blinks. no normal blinks or steady LED light then you have problem with module. Sometime the module works fine then later not working because the module get hotter due to poor ground (high resistance) or age. When the module get cool overnight, it will work fine.. you try to pull a module out of the dash and sniff around it (electrical burnt).

Thanks for that tip I didn't know that either. The red LED stays on all the time when the truck is off but when its running it goes off. So bad module makes sense.

Well I went back to Walfart to complain ... didn't think they would do anything and I was right ... the guy that did the paper work on it when I took it in the first time looked under the hood and was like ... uhhh I don't know what to tell ya I can't do anything about it do you want to talk to a manager" ... told him well yea I do!!! The district manager just happened to be there today ... so him and an assistant manager walked out and I told him what was going on and showed him everything ... he said it sounded like a module I needed to find the main control to check it out and they weren't equipped to handle something like that there but he used to have a similar system to that ... and did find that it was an additional GM security system that was added on after the factory alarm ... the speaker for it had GM on it in 2 places ... but that distract manager did noticed I had a screw in a tire I didn't know about it just happened to be on the up side of the tread when I parked ... he fixed that and didn't charge me for it ... looked like a sheet metal screw no idea where I picked that up from ...

I'm thinking I may just track the main control for that down and disconnect it and use the original factory alarm instead ... someone said they would start giving trouble usually after 5 years or so and its older than that ...
