Check fuse box for corrosion. Have definitely heard of corroded fuse boxes shorting and allowing power to continue through the circuits

Wont be fuse box if a fuse is corroded it wont make any difference this would not make the lights turn on and keep on the switch can only do this there is a comon fault with the light switches try taking the switch out and remove the rear wires if the lights go off its the switch could also be a relay if the relay has shorted or rusted over then this could cause the lights to stay on only other thing is the lighting circuit has a permanent live which will cause the lights to stay on but this is unlikley

97 firebird, won't turn over by key, headlights going up and down like crazy

look at the battery first.. there are two connections.. one a plus and one a minus,, check and clean both of these first make sure they are snug not loose and somewhat clean..check for a good charge also. these batteries go dead quickly in cold weather..usally when the headlights go dead the battery is dead also..(need to charge or jumpstart) if you have a charger connect it and let charge for a while(if not a second running car connected for a while will do) see if the battery is good, if not replace it.. repost findings..

Gave a jump start and now headlights don't work on a 2005 yukon denali

sound like battery has weak or battery terminals and post need cleaning. have battery charged and checked, if battery good. alternator not charging battery. if battery over 5 years old more likely battery is bad.if battery too weak head lights wont turn on battery dead this time of year if battery old. cold weather will finish it out.

2001 ford 250 s/dv-10turns over fine. wont start sometimes.when it starts it runs fine.seems like cold weather makes it worse.if it starts it wont die.started about a month ago and getting worse.

Make sure the battery doesn't have a dead cell or is over two years old first. Then depending on usage I would definately think about getting a new starter. I would suspect your battery first, due to the cold weather corrolation.

My windshield wipers and radio haven't worked since the jeep sat around for about 3 months in cold weather. I checked the fuses. Any advice what to do next?

Check the ignition key. When you start the engine, the key must go back by itself but because the cold, it get stuck so, just turn back the key a little.

Turn up the RF gain all the way and leave it.

RF gain is basically how open your receive is. There is really no reason ever to have it down unless you are trying to hear only close stations to you.

If you RF gain is up, your mic pins my be oxidized, or mic bad.
Try a different mic, and or clean the contacts in the connectors.
