Re: Signal light blow out
You have some torn/stretched wiring somewhere between the light and the radiator support, or a blown bulb now. Check for moisture in the lens as it may have broken the lens or the seal. if this happens lights will blow after a short time after replacing. the marker light wire is brown and the turn sig. wire is green. check the ground too. Good luck

Do you have trailer light hook-ups? Fifth wheel lighting and brakes, maybe a gooseneck ball? I would start with anything foreign to the vehicle(Not OEM).Most OEM wiring isn't subject to damage without help from you and I. :o) Hate to say it but we (or the guy who wired the truck for aftermarket lights) is sometimes the worst enemy.
The low tire pressure light gets a signal from each tire's (including the spare) sending unit in the valve stem. If all five of the tires are reinflated to the proper pressure the light will shut its self off. If the sensor was damaged when the tire was replaced it should be replaced with a new one.
Check the front and rear (although probably the rear) turn signal bulb socket for corrosion and/or water intrusion. If you find corrosion attempt to clean (but you will probably have to replace the socket and bulb). For water intrusion you will probably have to replace the break lamp assembly.
What may have happened is either the headlights wiring or the parking lights wiring somewhere along the wiring fused to the left turn signals wiring. Depending on if the turn signals go on when you put the parking lights on or the headlights on.
If the signals come on when you turn on the headlights than you only need to locate the light green wire that comes off the left turn signal harness.
Next follow that wire the entire way back to the firewall looking for another wire fused to that wire as you go.
If there are no signs of this you need to continue looking on the other side of the firewall all the way back to the turn signal and hazard flasher unit which is a black box that connects to a black harness located next to a grey harness behind the knee bolster.
But if the signals come on when you turn on the parking lights than you will also need to check the wiring from the rear left signal and follow that light green wire all the way back to the turn signal and hazard flasher unit.
This should fix your problem, but if not than your problem may lay within the the wiring between the turn signal/hazard switches and the turn signal and hazard flasher unit.
Also you may have a burnt circuit in the junction block. This block is where the light green from the rear left signal and front left signal meet. Don't have a description but if you cannot find it let me know and I will go out to the yard and look myself and let you know.
