I don't think the piece of rubber has anything to do with the functionality of the latch itself it usually there for keeping the latch quiet like no rattle or metal noise on the road.
Hope it helps

Chev is known for injector issues. You may have to remove the intake plenum and change one or 2 of the injectors. You can find them reasonably cheap online. You can test individual injectors with a small square 9 volt battery - never use a 12 volt car battery on electronic components as it's too much amperage.

It is quite likely that the linkage cables have come loose. Remove the rubber boot (cover) and visually inspect the 2 cables. If they appear properly connected, check the connection at the gearbox. This might be a simple matter of re-attaching the cables at some point. If not, you should have it inspected be a professional shop, as it is possible that the internal linkage has come apart.

Try replacing the blower motor resistor pack.

Ali, when you say won't start, do you mean it will not even crank, or does it crank and does not fire? Sounds like a computer or security issue .

normally it is the resistor,( relay) then resistor module then motor.
did you test the relay(I believe located under hood, relay/fuse center), If OK check plugs and wires for melting, damage and good connection, grounds should also be checked. Use a volt ohm meter to see if you are getting any power ti motor,etc.

Okay, how expensive could this fix be ? The easy answer would be with a question... how long is a piece of string ? There is really no way to tell... But stick with me and I will try to help you, as well as give you the greatest feeling of all. The ability to fix it yourself. This happens a lot to people who are mostly just drivers, not so much mechanics. The P 1515 code and the P 1516 code are both telling you the throttle positioning sensor isn't in the right place for the way the engine is running. Since it isn't running they most likely are just telling you that exactly... You are giving it gas but it isn't revving up like it should. So don't worry about those two yet...Now the P1345 is the Crankshaft/Camshaft positioning sensors telling they are not quite in line as they should be. This could mean it might need a look at the timing gears or chain or whatever it has to keep the valves and the pistons in tune in order to fire and expend the exhaust correctly. Look at your owners manuel and it will tell you how many miles your vehicle has when it is time to have this service done... But first before you do anything else.... Lets look about the P0014....This could fix the whole problem and if it does we will be done. Go out to your vehicle and CHECK THE OIL.... IF IT IS A QUART OR MORE LOW... THERE IS A SAFE SENSOR THAT CUTS OFF THE ENGINE... IT IS FOR THE PEOPLE TOO BUSY TO PAY ATTENTION TO THE STANDARD MAINTENANCE THAT YOUR MACHINE SO SORELY NEEDS... Try this and don't put more oil in it than it needs. This is almost worse than not enough. To check the oil just pull out the dip stick and wipe it very clean.... Then put it back in all the way, and pull it back out carefully, and notice where the bottome of the stick is wet with oil or dry. It will tell you how low it is. Then put exactly enough oil in it to register full on the dip stick. Hopefully this will conclude our troubles and you can be on your way. Thank you sir and good luck to you. Please let me know if it fixes it. If not we will go to the next step....If it does I will give you some tips and secrets to keep your baby going for a long time @[email protected] I am watching for you..

If your settings are correct and the engine is warm, it will be the thermostat.

One other it could be is a cylinder head Gasket. More than likely its your settings or thermostat

On the factory radio you need to use the seek (minutes) and scan (hours)...you need to turn the power off to the radio only...Press clock button, then move up and down using seek/scan...Should be in your owners manual too. Hope this helps.

Try tapping on the Throttle Position Sensor, you may need a new one.

No your car will still turn on with a bad cam sensor. Bad crank sensor would cause a no start. What code is popping up with the check engine light?
