Lighting issues
I have recently purchased a 98 c5, and had an alarm installed. after picking it up from the shop, i realized soon after that the front right drive light (yellow) and the front right blinker are now INOP. could this be a fuse issue, if so where the heck is the fuse? or is it more likely just the bulb. is the lighting an assembly or could i just replace the bulbs? Im new to the game, so any help/advice would be appreciated.

First thing is to fill out your profile that way any advice will be targeted to your car and your area. Some members wont even reply if your profile is blank.
The fact that both the DRL and the turn signal are out at the same time makes it likely that its just a bulb. It's a dual filament bulb that gives both functions. If it was a fuse it wouldn't just be one bulb thats inoperative. The DRL bulbs burn out regularly. Once it does you'll get a fast flash in the cockpit so you know you have a dead bulb. They're a PITA to change. You'll get three suggestions
Go in through the brake ducts - not easy with a Z06 or if you have screens
Go in through the bottom by taking out the bottom panel
The one that works for me is:
Turn on the headlights and back off one position to kill the lights.
Unscrew the 3 small screws on the black plastic housing around the headlight. Gently pull the housing clear. Reach down around the headlight unit and release the bulb holder. It unscrews counter clockwise but it has a plastic clip which you need to squeeze to release it. Change the bulb. Reseat the bulb holder and turn until it clicks back in place. Put the plastic housing back in place making sure to locate the small plastic tab in the bracket on the headlamp cover. Replace the 3 screws and close the lights.
10 minute job. Some guys have had the lights close if they’ve taken a while to do the fix. If you’re worried about that, disconnect the battery once the lights are up.
The bulb is a 4157NA
Some guys with big arms remove the hood adjusting screw for better access. Guys with even bigger arms have had to take off the headlight cover. Four torx screws (2 back, 1 each side). Take the back ones off first with the lamps down. Raise the lights and take the side ones out.
