My 2001 buick lesabre security light had been blinking for some time now. Sometimes it starts and sometimes it doesn't turn over at all.all tge lights on the dash work but, the cars doesn't click or..
Turn over at all. It on me yesterday and I
went back to get it today and it started right
up. No security light or check engine light
on. On the way home it just died...battery
light came on and it just cruised to a stop. I
tried to start it and it wouldn't start. So 8
pushed it the rest of the way home. Don't
know if it's a bad transponder key, ignition
or tdm bad. Frustrated
body control modules are known to do this and is a pretty common problem for any gm w-body platform car after about 150k. problem is, to diagnose it for sure, either run through the entire security system, or spend 400-800 dollars on an item that may not fix it.
