My headlights don't want to turn on immediately when I start my car it takes a few times for me to turn them on any chance its the relay or is it the switch if its the relay where is it located 2000 pontiac sunfire 2.2l 4 door

The only relay in the circuit is the DRL. Here is a description of how everything works.
Headlamp Circuit Description
The right hand headlamp fuse supplies battery positive voltage from the IP fuse block to the right headlamp. The left hand headlamp is fed battery positive voltage from the DRL relay. The low beam and high beam circuits are joined together and provide the body control module (BCM) with a low and high beam input. The low beam and high beam circuits continue to the headlamp switch. The headlamp switch includes the dimmer switch and the flash-to-pass switch. When the headlamp switch is placed in the headlight ON position a path to ground is provided. Depending on the position of the high/low beam (dimmer) switch, either the low or high beam circuit now have power and ground.
When the headlamp dimmer switch handle is pulled toward the driver, the flash-to-pass switch closes grounding the high beam circuit. Both high beams will remain on until the driver releases the switch handle.
The ambient light sensor is a light sensitive transistor that varies its voltage signal to the body control module (BCM) in response to changes to the outside (ambient) light level.
Daytime Running Lamps Circuit Description
The LT HDLP fuse in the IP fuse block supplies battery positive voltage to the daytime running lamp (DRL) relay coil circuit. The DRL relay switch contacts are connected to the LH headlamp battery feed circuit. When the headlamp switch is placed in the OFF position, the BCM will either turn on or off the daytime running lamps, in response to the changing light conditions. The BCM energizes the DRL relay, closing the switch contacts and applying ground in place of the battery feed circuit for the LH headlamp. Battery positive voltage flows from the RT HDLP fuse through the RH headlamp and LH headlamp to ground. The headlamps illuminate at a lower intensity.
Check your rt hdlmp fuse lt hdlmp fuse, drl relay.
if all ok may be your turn/headlamp switch assembly. Hope this helps.
