Turn signal makes the dash lights flash

The parking lights staying on and the left turn signal not working may not be related, the turn signal is probably a burned out bulb, turn on the left signal and see if all the bulbs light up if not replace the burnt one, if they all light, the turn signal flasher may be at fault ( it can work with one side and not the other), as far as the parking lights staying on, check the door "pin" switch that controls the interior lights (are the interior lights staying on too?), since the chimes are staying on even with the keys on , I would suspect the door pin switch, probably the drivers side. I believe there may be a timer on the parking lights that turn them off after several seconds after the door is closed, this may be at fault if not the pin switch. newer cars and trucks also leave the reverse lights on for a while after the door is closed.

Have you checked all the bulbs (rear as well as front)?

The fast dash turn signal indicator is telling you one of the lamps is faulty. Check all of them and you will most likely find your problem.

check fuses or the turn signal switch is bad

On my 95 Chevy 1500, the 4way flasher is located in fuse panel on firewall driver side under dash. To get to the turn signal flasher, remove the bottom dash panel and the entire ash tray compartment. I also removed the cup holder unit to allow light. The turn signal flasher was located just below the the radio and AC area. Mine was wrapped in tape from the factory, but if you turn the turn signals on you will feel the vibration and be able to locate it from the sound.

turn your emer signl hear the sound underneath the left side of the dash,touch it,that is the one.

Replace the flasher relay. It is usually under the dash. Follow the clicking sound when the flasher is on. It just unplugs.

I had an issue like this one on a 2007 Colorado. I assume you mean the turn signal indicator inside the truck lights up. It was a bad bulb. think it was the turn signal bulb on the side that is lighting up. As for the gear indication being dim there is more than one bulb that lights them up and one may have blown. I hope this helps.

More than likely a bad ground in the wiring harness's. Have you changed your transmission, Alternator, or starter? Or added a trailer plug on the bumper?

There is a light sensor that tells the truck if it is night or day on the dash. Make sure that is it not covered up. If is is not then you may have a bad sensor. It sounds like the sensor is telling the truck that it is night every time the truck is running.

Start the tuck with the park brake on to see if the light come on when it starts. If they do you have a bad relay if not it is most likely that sensor on the dash.

More than likely it is going to be your clock spring behind the steering wheel.
