Guys. Please help. I have replaced all interior and probably missed something. When i lock car it beeps once. MEaning that there is some error. Door, hood, trunk swithes are OK. Because if i leave open any of them - car wont lock. Meaning there is some other error. What do you have in mind: center console switch ? what is that?

Yes, there is a wire set going to the center console. That's most likely it

Just lift the arm rest lid up and check the latch area of the center console. There are two slot. One accepting the lid latch, the other is a microswitch. It's likely it's not working or there's wiring problem (need to remove the center console to get to it).

I now have this annoying issue. I took my CDR-220 out to add the Aux In and when I put it back together I get the single beep. I pulled the radio again and noticed this piece swinging free with the Brown/Blue wire attached. It seems when some have disconnected just the wire and taped it up it has fixed the alarm issue for some and not others in my reading. Does anyone know if this works on resistance or if it is strictly a contact point when the metal of the radio contacts this it sets the alarm off? I thought about leaving it attached and just taping the whole piece. Any thoughts?

Update on the Radio Alarm wiring. Ok, I inspected the Brown/Blue wire and didn't see any cuts so I taped the end and reinstalled the radio. I locked the car with the fob and beep. So I reconnected the piece below and taped it up, reinstalled the radio locked the car with the fob and NO beep. I tried it a few times with no issues and no rogue car alarm over night so I think it is fixed. So I am not sure how all this fits but I am glad it is working correctly now.

On my 99 C2, I disconnected the seperate alarm horn. It's located near the battery on the driver's side. I got tired of chasing the problem.

Aloha! I am having the same problems with my 1999 996. AND my FOB doesn't work. So I've been either leaving my car unlocked (scary) or locking it (sometimes I get a single horn beep, sometimes I don't) and the alarm still goes off. My mechanic said it was because the interior sensor was "seeing" a lighter color in my interior vs standard black. He suggested I cover the eye with a black cloth. STILL goes off. I need to be able to simply lock my car. Don't really care if the alarm is armed (would prefer it's not since it likes to go off at it's own whim). Can I do the lock, unlock, and don't touch to auto relock solution suggested above by using the key in the door? Any help is appreciated.

What color is this wire? Was it attached to the factory radio? I had an aftermarket radio installed and now the alarm is going off. I need to know the fix on this as I cannot leave the car unlocked.

@smorris can you describe what your door window issue was and how you fixed it as I'm having exactly this same double beep issue since having my passenger door resprayed and it's super annoying! Many thanks 😁

smorris last post 10 years ago in 2011. Don't think you will hear from him, but who knows? GL
BTW, did they remove the door card or window to respray the door?

Judder

Thanks @Joe996 and good point!

re: the door yes as it was being straightened as well they would have definitely removed the door card, and I'm guessing the window actuator too - where about's are the switches that the alarm checks?

DBJoe996

There are many microswitches in the door - inner and outer door handle microswitches and several in the door latch mechanism. Does the window drop occur when you pull on either the exterior door handle or interior door handle? You should pull the door card off and make sure all the switches are connected. Read up on how to remove the door card and side air bag. Disconnect battery before proceeding.

Judder

Good idea - I tested both doors from outside and inside and the window drops correctly in all cases so I think we can rule out the handle as being the problem.

I also locked the car and tested the handles and they are correctly inoperative when locked so maybe it is one of the micro switches in the door lock not informing the alarm that the door is locked correctly?

DBJoe996

There are a number of microswitches in the door latch. I would check it with Durametric first so you are not on a wild goose chase. See this thread here https://rennlist.com/forums/996-foru...-detailed.html
