first u must put the engine to the top dead center by lining up the marks on the front pully of the crankshaft also make sure the marks are on the intake stroke and not the exhaust stroke by taking out the number one spark plug and putting a small piece of rag in the hole . not all the way in leave some hanging out. now rotate the crank by 5/8 socket and breaker bar clockwise until you hear a pop as the number one piston blows out the rag from the plug hole signaling that the piston is on the intake stroke .check marks on the pully for exact timing .next get the distributor and drop in the hole making sure to point the rotor to the direction of the number one piston also making sure to seat the distributor all the way down leaving the keeper loose to align rotor to the number one spark plug wire on the cap . install wires to spark plugs .next have someone crank the engine while you are turning the distributor slightly til you hear the motor start this might take a few times to get correctand a timing light will be needed for final adjustment.

Hello James,
It sounds like either you have a blown fuse or relay under the hood. Or it may be your keyfob. With the Interior lights and the liftgate not working. I want to say it may be a fuse. Have you hooked anything new upon the vehicle? If so you might have shorted something out. Have you recently put a receiver hitch on it? If so there is a possibility you could have got your wires pinched in it, or you may have lost a ground wire somewhere in your wiring. I'm sure you have probably already checked your fuses, but did you check both boxes? The one under the hood and the one under the dash? Check them and go from there to your wiring and check your battery in your Fob. You can make sure your fob hasn't messed up by taking it to someone with the right scan tool and reprogram it to your vehicle. Try that and see what you come up with.

Yes, a inoperable relay will cause a turn signal failure. But it isnt the only reason. If you need more information please write back. If you do, please write back with specific details about the issue and what you have done and tried so far. Good luck.

You should have a fuse box located to the left of the steering column by your left knee. If it's not there open your drivers door all the way and see if the panel on the end of your dash doesn't remove giving access to it. Most all GMs are there or under the dash by your left knee. Relays are a couple places. The main relay box should be under the hood on the drivers side. On or close to the inner fender well. But the ones for the blower motor are usually located behind the glove box on the ********* housing where the Heater & A/C cores are located.
Hope this helps you.

Normally this should be under the steering column, on the fuse box

Replace the blower motor resistor located in the blower housing under the dash on the passenger side and you will be good to go.
