Question:
Hi, I have a 2002 pontiac firebird. Have not had any problems till tonight. It was a bit cold outside (San Francisco, California) and when I pressed the key-chain button to open the car, it would not open. I noticed that even the radio-theft deterrent red LED that flashes inside had stopped. I got into the car manually and tried to put the key in ready position, but no indicators or lights came on and when trying to start it, it did not start.
Could this be because it was cold outside? I have not used the car in 2 days. Recently serviced (oil etc) by Jiffy Lube.
Im planning to lookup the battery "eye" (hydrometer) tomorrow morning and try again in daylight.
Any suggestions on what could be the problem? Also, 2 days ago I used a recently purchased seat-warmer device while the car was running, for approx an hour's drive. It couldnt be that, could it ?

Hay fellow San Franciscan and firebird owner. Except I have a 2001 trans am ws6. My best suggestion is to but your bat. on a trickle charger over night. Have the bat load tested. to verify that it is good. Should hold min 9.6 v under load at 200amps 15 seconds. Check for loose or corroded terminals. Just for your info.That little green lite don't mean much. A bat has 6 cells. That green lite only measures the electrolyte of one cell. There might be a short or u can have defective plates.Either way if your bat. is good. Check your charging system. simple way is to just but a voltmeter on bat. should read 12.5v enginee off bat fully charged. Start engin and check meter. should read 13v or above apply load. (turn lights or accessories) on. meter should rise around15v. If all is working properly. If no failures are found than it's time to look for a parasitic draw. this can take some time and should be done by a qualified tech. It involves looking for anything that should turn off after the key is removed. Since we are dealing with a late model it should be noted that it has in it's design a function known as keep alive memory That basically means that the BCM runs a check on the cars electric and security systems and turns every thing that is not supposed to be on, off. It allows only programed functions to operate.Like the sentry system. As for your seat warmer.If the car is running the alt will pick up the extra load.Yes and Yes and No and No
I have a 2005 silverado 4x4 regular cab with a 4.8 L V8,with modifications?
Yes theres no power (no dash lights) so in all likelihood yes its a flat battery so first impressions are that 1 something was left on (i.e. light, seat warmer) 2 the battery is faulty
I lost my car keys. How much can it cost me to get new ones?
No the battery wouldn't go dead because you used the seat warmer while the car was running and No the cold wouldn't drain your battery either
The fault is definitely electrical but I believe youre right in your suspicions about the seat warmer and the battery. my guess is however youve wired the warmer is the problem. Disconnect it and jump start your battery and you should be sweet :)
What is gas (Petrol) going for out your way?
The alarm probably froze up, went off, and drained the battery, the seat warmer, and jiffy lube are co-inncedental, check the battery and connections, try throwing a quick charge on the battery with a small battery charger.on a 92 Pontiac Bonneville SE how would i find out if it is supercharge or not?
could be bad battery or you might need to have it charged2000 Ford F-150, Won't shift into 4x4?
The easy way out is to jump start the car and take it to an auto parts store .Most of them will test your battery for freeDoes my wheel cylinder need replacing?
This has happened to me twice with two different cars-Check the starterAlso check for loose battery cable.
Do you have a lighted box between the seats that might have been left open and the light drained the Batt?

probably battery,5yrs old.the other things are probably coincidence. If the battery is old and weak the cold could have finished it offHard to say what caused it, but it's probably time for a new battery anyway. I doubt the seat warmer hurt the battery, but it is 5 years old. They aren't that expensive, just shop around the auto parts places with your phone and you should be able to find one for less than 50 bucks easily.

How old is the battrey ? To me it sounds like your Batt was getting old then you started drawing extra amps away from the Batt now add in the cool weather and maybe you used the rear window defogger that draws alot of amps now add in the in car heater with a weak Batt and presto you have a dead battI think you've killed the battery. Try a jump-start or (if it's a manual) a push-start to get it going for now, and replace the battery at the first possible opportunity.
Also, I think it could well have been the seat warmer. When the engine is running, electrical loads do run off the battery, it's just that the battery is being charged by the alternator at the same time. If the seat warmer was drawing too much power, the battery might not have been able to charge.
If the battery's not been replaced in a few years, now might be the best time anyway - if your weather is anything like here (UK) then this is just the start of winter, and batteries don't like cold! My Peugeot and mother's van have both just had new ones.
