QuestionSaturn replaced the BCM and it fixed all the problems except my remote to open the doors and set the alarm still doesn't work. I'll tackle that problem next month since it must be unrelated to BCM. But all other wacky problems solved. Thank you for your help.

Question -
I have a 2000 LS1 Saturn-3 years ago I was having trouble with the car locking me out for 10 minutes because the security system didn't recoginize the key. Saturn near me replaced the BCM (under warranty) and sold me a new remote. This did not stop the problem. Finally a tech replaced the ignition cylinder and this fixed the problem. NOW, my coolant light is on and temp goes to HOT. ALSO, the Security light goes on although the car starts okay, then the service light, the gas gauge goes to E (although plenty of gas) and sometimes then the Temp goes to C - I've had the odomotor stop working on occassion as well. My fob works intermitantly. When running the fan for the air conditioner blows but not cold air. The Saturn dealer suggests replacing the BCM (again!) but I am afraid that will not fix my problem. I was thinking of having the igition cylinder replaced again sine it fixed the problem last time. Any advice would be greatly appreciated.
Thank you for your time!

Jennifer,
WELCOME TO THE WORLD OF THE SATURN L-SERIES!!!!!!! I say that last statement with an emphasis on sarcasm. I am a huge proponent of Saturn vehicles, but wait, there's a difference here. The L-Series might have been produced at a Saturn assembly plant, but the vehicle has no similarities to the Saturn line of years ago. The 2000 L-Series is BY FAR the worst vehicle that GM has produced in a long time. That's right, the L-Series was forced upon Saturn by General Motors (because none of the other GM car lines would take it). As much as you might want to, please don't berate the Saturn guys. They do the best they can with the vehicles that they are given. It's not their fault that GM over-hyped and under-engineered that vehicle.
With that being said:
The Body Control Module that sits atop your glove box is made by Motorolla (only because they were the lowest bidder at the time). If Delphi (AC Delco) would have made it these random and sometimes wierd problems would not happen. I have replaced at least four hundred of these infernal contraptions if I've replaced a single one at all. The problem you are having is in the BCM. Please don't have the cylinder housing (passlock sensor) replaced first. I'm not saying that the passlock sensor could not be bad, but I would start at the BCM first. Just to make sure that I know the story. You have not had a problem of this nature since your repair of three years ago. This being true, you have an inoperative BCM. The BCM in your vehicle controls almost everything related to the inside of your vehicle. Lights, gauges and HVAC controls are all routed through the BCM. Anyway, if I keep going I'll get on a soapbox about Motorolla's BCM. I know that the BCM is not cheap, but that's where I'd start if I were you. Please let me know how this turns out. I am always glad to hear of this kind of situation turning out allright. Hope this helps Jennifer,
Chris
AnswerJennifer,
TAKE THAT CAR BACK, to the service facility. Part of the BCM replacement procedure is to reprogram the key fobs (remotes). That's the last thing a technician should do before giving your vehicle back to you. If your key fobs need a new battery, they cost a whopping $5, and your facility should have them around. If the key fobs were inop when the technician replaced your BCM, he should've caught it. My money is on him not having the key fobs to reprogram, or him not reprogramming them all together. At any rate, if you have key fobs, take your vehicle back and have them reprogrammed. They should not charge you for this, so don't let them tell you that you owe for this procedure.
