About Rob Painter
Expertise
Alarm system questions cannot be answered on this forum. These systems are not what I can answer. Without being physically at the vehicle and not knowing what kind of electrical service has been done on the vehicle, there is no possible way to give an accurate answer over the internet.
My expertise is in Ignition/key based anti-theft systems. These issues include GM VATS (resistor chip in key blade) PASSLOCK (MRD)-ignition lock rotation based, no special ignition key and the PKIII Transponder (computer chip in key) systems. These systems are not alarm based and are integral with the starting of the engine.
This is why I cannot diagnose alarm problems without physically looking at the vehicle:
Alarm systems are a completely different annimal than ignition key/lock based anti-theft system. Many alarm questions come from vehicles 10 years old, and since older, many hands that had been involved over the years.I am an expert in all GM factory (ignition/key based)systems. Alarm system questions pose to many situations beyond my knowledge as to what has been done to the vehicle over the years. Some guy may have actually wired the stereo into the alarm system. Who knows? Over my past 30 years in vehicle wiring repair, I have seen unbelievable wiring disaters done by guys that consider themselves "mechanics." I have seen stereos and alarms intalled using surgical tape. I have seen modules burn up, un-fused circuits, wiring jambed between the doors and even lamp cord used for a starter kill. To answer alarm questions over the internet without examining the vehicle is like asking; What does it take to remove a dent?

Expert: Rob Painter - 10/25/2009
Question
Hi! My 94 SLS has a leak taht I can't quite find the source ot. Lately when it rains, my back floor boards fill up with water. I even got all the water all out this morning and within a few hours I had standing water again. I think taht it could be my sunroof, but my headliner and areas surrounding the sunroof are dry. Could it be a seal or drain system? And if so, can I fix it myself? Thanks!
Answer
Hello,
Water leaks are the worst next to a rattle to repair. You can have where a seam is not sealed properly in the front and it manages to fill the trunk.
First, the bad news is that your interior is now filled with bacteria and eventually you will have electrical problems because humidity goes everywhere.
No matter how good of shop vac you have, it will not remove the water from the steel floor and jute underlayment. Your car will stink in warm weather and you don't want to be breathing the mold!
The seats have got to come out. The carpet has to be removed, shampooed and sun dryed. The jute underlayment that will be soaked forever has to be removed. The rubber plugs have to be removed from the floor. Anti-bacterial soap should be used to clean the steel floor. Once dry, sprinkle baking soda, carpet freshner, whatever. Install new jute you bought from auto upholstry store (very cheap) then the carpet. If you have cloth seats, you will want to shampoo them too.
None of this however can be done until you find the leak.
Send me details of the vehicle: make, model etc. Has it been in a collision? My personal email is robo14@aol.com and maybe I can give you some ideas of what to look for. The moon roofs have vent tubes. One could be broken or plugged filling the car that way and you would never see a leak at the headliner.
