If the signal lights work then the wiring and socket and obviously the bulbs are good which leaves the brake light switch or wiring at the brake switch is bad.

Have you verified that all the ground wires are good?
SOURCE: need to replace the turn
Have you checked the fuses check for a blown parking light fuse.The reason the dash lights turn off is so that you'll know when the tail lights are not working so that no one rearends you.
SOURCE: my taillights are not working.
grab a flash light and look for blackened fuses or grab a test light, hook the negative to the battery and just touch the sharp end to each fuse, if it doesn't light up then that's it. good luck

The speedometer and odo meter not working relates to faulty speed sensor located on transmission and problem with odo meter cable and gears.But if speed sensor and odometer cables and gears all checked ok, then problem relates to faulty instrument cluster board.Its getting short or the connection to the back of instrument cluster board is loose.--------- The first t5hing to be tried is take the cluster board out and inspect the connections, disconnect the connectors to the back of the cluster board and clean the connections and reconnect it tightly and see if that helps.If not helping then this problem relates to short in cluster board, new cluster board is very costly, but in most cases the cluster board gets easily repaired, the local auto repair parts store have good idea for where to get cluster board repaired.----------------
Also turn signal, cruise control and air conditioner problem relates to different possibilities, in that case the turn signal switch, the wiring's, the cruise control board, fuses/ relay under hood and in the instrument panel fuse box needs to be inspected.----------------
But there are many possibilities for all this problem. If you go troubleshooting each and every possibility it will be time confusing and will cost you high/ heavy to get your problem solved.----------
But there is one good thing in this problems.That good thing is , you have check engine ;light ON.This engine light comes ON , when there is error code stored in cars computer memory.---------
So the best advise is to get the car scanned first.In scanning it will give you few error codes.As per each error code it will point you towards the faulty part that is causing the problem.--------- One more good this is, that at autozone service centers is free to get car scanned.Yes, they dont charge for scanning and giving you error codes, but they charge only for parts and its labor, if replaced from them.Otherwise there is no charge for scanning.So the first thing you can do is get the car scanned. And go from there, towards troubleshooting.----- So as per error code, you can directly look towards that parts only, which are causing the problem.-------
This will help.Thanks.Helpmech.
