I have a 94 PontiacGrandAm with a loose dashboard whats the best way to get it tight

check the fuse first off. More commonly than not a corroded ground connection is usually the source of the problem on dashboard gauges if they have all stopped working at the same time. Also I've seen where plug in the back of the cluster becomes loose. but not loose with a plugs falling out but loose Worthy pins in the molex connector are not making suitable contact depends on the other side of the molex connectors. I've used needle nose pliers to gently twist the flat pins a little catty-cornered so they will jam into their respective contacts more tightly. Also you'll need to make sure the cluster is getting power, everyday should be powered off the same wire.

check wire on stater

you push on the belt and should have a half of inch play on it...

Shift cables came loose or off you will need to locate the shift cables and ensure they are tight and not broke sometimes they will break so you may need to replace adjust and tighten up the bracket.

Weird,sounds like your battery connections are possibly loose, but
the car wouldn't start properly, or at all, if this was the case. You might just have a loose connection to the dashboard controls?
If you are up to the task, I'd remove the guage console,if you can,and make sure all the connections are tight. Good luck.

I can think of two possibilities. 1) The gear selector needs a slight adjustment 2) the bulb for the gear selector is loose or loosing it's ground

sounds as if you have a poor conection i would trace the circuit and make sure all your connections are clean and tight ......if this does not resolve your problem there is a posibility that your inst panel cluster is faulty....good luck

sheck and make sure battery cables are tight. also if vehicle runs a timing belt u may have skipped the timing due to belt wear.

Probably a loose wire. Make sure batter cables are tight and check for lose ground wires.

change the fuel cap
