Lights and speedometer acting weird

There are a total of six fuses that control exterior lights and dash lights. Check all of these Fuses: 10, 21, 3, 7, 13, 33
Does the high mount stop light work when you apply the brakes?

you may just have a weak battery, or a battery that is not designed for the cold. I would recommend having your battery test at your local autoparts store.

has the battery been checked?

Sometimes this works, ABS light on, check engine light on, speedometer not working, and the automatics start shifting hard or not shifting at all? One bolt and the part is cheap, its weird how one part controls so much.

check the connections and the starter sylanoid on the passengerside inner fender may need replaced

check the main fuse, and relay, if ok check for power to the starter solynoid if yes then starter may be faulty. check power to switch also

sounds like a fuse

not sure but in the newer cars the ground wires seem to be most important becouse the ecm is working through the groung side. i would start by finding ALL the grounds and cleaning and tighting them

first of all make sure battery is fully charged auto zone will test batteries for free but if you can get it jumped and running while it is running take the positive side cable off the battery and if it dies then it is the alternator and also look at the condition of the drive belt but if you do all this and the truck does not start spray very little starter fluid in the throttle body if it starts ask yourself when was last time I changed the fuel filter and also have someone to be back by the gas tank to see if you can hear the pump and check out the fuel pump relay which is normally under the hood on the drivers side before changing the fuel pump

i think it is the alternator because the idiot light is connected to your regulator of your alternator. it is an indication that your alternator is not charging anymore.

tnx 4 using fixya,
