1989 300E ALARM PROBLEM
 

Hello, recently (yesterday) i brought my car to the dealership for a free 54 point inspection. After leaving the dealership, when i got home i tried locking the doors and the alarm starts going off. Every time i tried locking the doors, either driver or passenger side. So i checked the contact under hood as in i pressed it manually while i tried locking it to see if it has contact and that didn't work. So i brought it back there and they looked at it and said they would need more time to go through each contact. I'm not necessarily blaming them because i don't know what happened. But i do need this fixed. It has been raining for the past 2 days and this morning when i tried it in the garage it didn't happen so i thought it was fixed. But then later it happened again. Now it's doing it constantly
Has anyone had this happen to them. How do i fix this on my own??

Disable the alarm...

Look for my how-to thread...i has detailed instructions.....

good luck
