its 1 of 2 things.
1: the fuel is low, use a dip stick, if gauge reads ok.
2; or the tank sender is bad, but gauge reads wrong.
3: the guage wire is disconnected, cut or corroded connections.
id say gas guage is broken i have seen lots of chevys around that year go bad. got to change whole fuel pump which is in the tank. not to bad just got to lift bed some. not sayin that is the problem because of the other things happening but just saying it may be. as for rest i have no clue.
I would check my oil pressure gauge and the oil level as well. the fuel level guage also malfunctions on those models so make sure it is working properly and not floating from full to empty that will cause the light to come on as well as overheating of the engine(low coolant levels)low oil level,low fuel level,and low charging volts from your alternator.if all is well suspect a short in dash.

I found this site, no mention of the fan in a cylinder, but I'll let you figure it out. Hope this helps. http://www.trueblueford.com/ed_pages/EDfalcon_fairmont.html
I had a 2001 silverado 2500 h.d. with the same problems. I took it to a gear head and he found that the emergency brake cable was loose causing it to trigger the warning light on the dash. As far as the low fuel guage I took it back to the gear head and he found that the float in the gas tank was broken causing the low fuel light to come on. The float wasnt a big deal until I lost track of mileage and ran the tank dry.
When testing a fuel guage you should disconnect the wires to it,guage should read over full,ground the float wire,turn off key then turn back on should read empty.You have to cycle the key for guage to move.If still inop the wire is broken in the harness between the tank and the dash.Voltage on the float wire is low.When tested with a test light it will barely light the light and pulsate.This test indicates the wiring is good.
I took the vehicle to the Jeep dealership, and the problem went away before they could check it out. They are going to check wiriing next, because the check engine light went out on its own, and the fuel gage began working corectly on its own. Not sure what caused it, but hope to have an answer from the dealer.
