1999 Chevy 1500 LS Battery comes on when humid

My 1999 1500 LS pick up with 350 engine has the battery light coming on when very humid or after a lot of rain. Also, sometimes but not always acts like it doesn't want to start...but on second or third try starts fine. Battery light goes out after warming or humidity is lower. Volt meter has bounced around some, but then stabilizes where it should be. I have had it act like a dead battery on first try and then start like nothing is wrong...driving me crazy!!

Make sure all your battery connections are clean. take them off the battery and clean them and the posts on the battery .. also check the ground from the battery to the block and make sure its tight .. also check to see if the cable is tight on the starter when the engine is cold.. then check the back of the alternator to see if that positive line is tight on the alternator .. holler if you need more Jerry

1999 1500 ls abs and brake light on at same time then off just sometime


WHEN YOU SEE BOTH LIGHTS AT THE SAME TIME YOU ARE HAVING BRAKE FAILURE EITHER MASTER CYLINDER FAILING OR ABS BRAKE MODULATOR FAILING.CHECK BRAKE FLUID LEVEL IN BRAKE MASTERCYLINDER. IF BRAKE FLUID LEVEL OKAY. I HAVE SEEN CASES WHERE ALTERNATOR FAILING CAUSING BATTERY VOLTS TO DROP AT 11.8 VOLTS CHECK BATTERY VOLTS AT BATTERY WHILE ENGINE RUNNING SHOULD BE 13.5 TO 14.5 VOLTS AT BATTERY WITH ENGINE RUNNING.IF BATTERY POWER IS OKAY.MORE LIKELY BRAKE MASTERCYLINDER AND ABS MODULATOR COULD BE FAILING. TAKE VECHICLE TO A GARAGE LET THEM CODE SCAN TO SEE WHAT CAUSING ABS AND BRAKE LIGHT TO COME ON.CODE SCANNING WILL SAVE YOU TIME AND MONEY.

How do you change a running light on a 1999 chevy silverado


pick up your hood, each headlight has a rod L shaped on the right and left end of the light. they look

like latches. unlatch the rods and pull them straight up. once the rods are removed you can pull out

the headlight assembly and you have access to your running lights. on the battery side, you may have

to remove the battery. good luck!

Chevy silerado 1500 350 v-8 where do


On the low pressure side of your system. The high pressure is by the battery on the aluminum tube hooked up to the radiator. Not that one!! But the other aluminum tube hooked up to your firewall going into the cab. Both of em looks alike. Is a quick coupler fitting with a black cap on it.

Battery light comes on when damp


I would check belt to alternator pulley slippage when moisture is high. Belt might be due for replacement. Hope this helps
