Help 1999 silverado will not start just makes clicking noises. Lights and radio works. Clock on radio was reset.

What lights ? And won't start how ? The clicking is more then likely a relay or a module of some sort . When you turn the key to the start position does the start engage an spin the motor ? Or nothing happens , a crank no start or no crank no start !

is it making a click noise . if so .that is a bad starter

Does the battery have a good charge in it. Possible bad starter to.

This sounds somewhat similar to a problem I had with my 1999 Saturn SL2. There was "burning and arching" on the fusebox and it was replaced. The first few times my car would make an extra beep noise when locked or unlocked and I believe the radio/clock had to be reset. The problem got worse although sporadic. Eventually the car wouldn't start - not even making a clicking noise and a big variety of electrical components would not work or didn't sound right.

Make sure your battery is fully charged and all battery connections are clean and tight. If the vehicle still makes the clicking noise when you try to start it, then it is your starter solenoid.

IF U HAVE THE RT SWITCH, CHECK FOR A BAD GROUND WIRE, START WITH THE TAIL LITES, CHARLIE

Does your radio stations also reset at start-up or sometimes do they reset? If you battery is weak and it takes a lot of power to start your vehicle it could reset your clock and sometimes clear your radio stations as well.

When you try and start the vehicle does all the lights and radio and stuff go off? And does the starter make any weird noises when you try and start it? I would go to the parts store and ask them to check your battery if you can drive it there. lol..........they will be happy to check it out for you. Still acts like it could be a battery issue.

there is a plug at the back of the radio connecting it to the vehicle wiring loom. If you can get at thes plug, either from below or by removing the radio unit, make sure the plug is tight and secure. I can't think that the amp has gone or you would have lost all sound, so this is more than likely the problem.

it sounds like you need a regulator for your alternater it is reversing polarity there for draining your battery and reseting the clock. it is located on the back of your alternator.hope this could help.
