Have you tried the door key in BOTH doors?

if it was a fuse they would all stop working as it is a electronic cluster. most likely a gauge fault but you might run down the wiring with a volt meter, where the voltage stops is where the issue is. also you might verify you fuel sender is working and check voltage to battery while running

I would pull the fuel filter loacted on the frame and blow through it. If it has any resistance, it is plugged and this is the cause of your problems. Let me know what you find.

You must remove the seat from the truck, then remove the drive motors that control the adjustment you wish to make, then set the seat to where you want it and reinstall the drive motors. There is no other way. I would suggest you try and fix the problem with the seat, often it is just the switch that is bad.

When this warning light flashes it means the fluid (ATF) temperature of the transmission have reached a level that is detrimental to the operation of the transmission and damage will occur if the cause is not corrected. The causes can be overloading (towing) the vehicle, severe operational circumstances such as high air temps. Other common causes are excessive slippage of the transmission due to worn clutch packs or a defective torque converter. Also the TFT (trans fluid temperature sensor) can malfunction and send a false signal to transmission control module (TCM) and set the warning light. I would not ignore this warning, have it checked by a transmission shop or the dealer.

If I were to make an educated guess I'd say some where in the vecenity of the fuse box

most likely your fuel pump has failed!
