In the 1999 Chevy Silverado 1500, the headlights are not designed to be on all the time by default. They are typically controlled manually by the driver using the headlight switch, although some vehicles may have a daytime running lights (DRL) feature. If the headlights are continuously on, it could be due to a modification or wiring issue, and it's recommended to consult the vehicle's manual and seek professional assistance if needed.

First make sure the fluid is full. If it is then you have internal problems. Possibly the linkage or oil pressure .

By indicator lamps ,you mean warning lamps (check engine,oil,battery, air bag,etc ?

-Check "headLight fuse"-Check connector at the headlight.-Check the bulb. (It could burn out)Mai

sounds like you have a coolant leak, if coolant is low it will cause both of your symtoms as to where it is coming from, there are many places but common ones are hoses/clamps, water pump or radiator.

It is likely the charcoal canister for the fuel tank vapors, and all part of EPA regs.

I just had the same issue with a 1999 2500HD and the vibration got worse above 50 mph. Problem was resolved with a new driveshaft. Old one (aluminum) was badly out of true and the problem didn't really occur until I had the U joints changed - then bent driveshaft vibration was noticeable. New driveshaft resolved issue.

are there splines on both ends ? .... the splines will go toward the transmission.

What is the CODE for.? The radio anti theft code.? I know that with my old Honda Accord the dealer had the code archived in their system. I changed my battery and had to have the code to put in the radio.. I called the car dealership that sold me the car. All I had to do was give them my information and they looked up the code ID..
I would imagine that GM automobiles work the same way. I hope this helps you..
