MY 1999 LUMINA ACCELERATES WHEN TURNED ON. HAVE TO TURN IT OFF AND ON SO IT WILL STOP

Sounds like you turned on your emergency flashers somehow without knowing it. The button should be on your steering column. Otherwise, find the flasher control under the dash by following the clicking noise and unplug it. Then go buy a new flasher control.

stop light switch is under the brake pedal

Check the brake light fuse if its ok then check the bulbs if they are ok then check the brake light switch. Good luck

I was having similar issues with my '95 Lumina. It started out with the passenger side brake light not working and the turn signal switch on the column acting funny.
Eventually, someone pulled-up next to me and told me that I had no rear lights at all.
It turned out to be the turn signal switch in the sterring column.
Hope this helps.

because aaa can jump start it and you can't sounds like maybe the battery cables are curroided (dirty)
in-between the battery post and the clamps, clean the battery terminals and charge your battery as a loose conection can run down even a new battery

check the throttle position sensor.

if no brake lights are working,not even the high stop light in the rear window,And you have checked the brake lights fuse with a test light,it will be time to check the stop light switch located on brake pedal under dash.

no fan comes on when engine cold start up .but it will come on when you turn on air conditioning or defrost on .if engine idling a while when temp get 190 degree the fan will kick on.if over heating you got air in system .wait until cools check coolant add more .crank engine let it idle few. minutes when start warming up turn off engine wait a while before removing radiator cap so you wont get scald.add more coolant .crank it again starting warming up turn off engine wait a while .add coolant .keep doing this procedure until your coolant stop dropping off .if you do this more than 6 times you got a leak some where.check crank level for signs.if oil level higher than normal.if everything looking good.when engine cool make sure add coolant to over flow jug cold level mark.

try brake switch under the brake pedal and check all fuses.
