If your looking for the Intake Air Temp/Manifold Absolute Pressure sensor (IAT/MAP)(2003 model year and up) It is on the top of the intake manifold, just to the left of the #3 injector fuel line. There are 2 small Torx screws holding it.

The A/C relay is in the integrated power module under the hood.pull the relay for the A/C check pin #85 for activation request form the pcm( if you turn the relay over and look at the spade connectors they will have a number designation you are going to test pin #85) then with a test light check pin #85 for a good ground ( the pcm supplies the ground to that circuit) with the engine running then have someone turn the A/C button on and off inside the vehicle. if you do not have a ground being supplied by the pcm then you should probably take it to a dealership for diagnoses of failed component. if you do have a good request then test pin #30 and #86 for power with a test light .

no idea to be truthfull and i would lying if i posted that i knew it all ,i dont its that simple .these modern vehicles have so much electronics you need a electrical university degree not my simple motor vehicle technician .I can only hazard a guess and that would be a crank sensor ? fuel pump pressure or a breakdown of a chip in the computer .I do fell this would cost more to repair than the vehicle is worth ,unless your in spain of course so i would advise you to trade this one in and buy a new truck .

Hey Fastrick,, this sounds serious... if I read this right..you may have a column that is coming apart inside...something has broken and is causing these issues.. PLEASE take it to a QUALIFIED professional and get it checked ASAP ... this COULD EASILY be serious.. and leave you stranded .... and I have seen "thermal events" from this!!

What color is the fluid ?

Sounds like the horn button on the steering wheel has gone to ground. Look at the harness running up the steering column to see if any wires look pinched or cut.

Seen this "mystery drain" many times. Check spark at the battery to see how big the drain is. For this simple test, blow away any (explosive) battery charging fumes. Leave one terminal on and gently touch the other to its post in fairly dark surroundings. Then try it again with the wires taken off the alternator. Your spark is now probably much less. Usually bad diodes leaking electricity backwards through the alternator cause this drain. Replace the alternator or the diode pack inside it. Some mechanics recommend actually measuring the drain.... hahaha. OK whatever.

UNHOOK YOUR NEGATIVE CABLE ON BATTERY AND TURN AND HOLD KEY TO START POSITION FOR A TEN SECOND COUNT WAIT 15 MINUTES AND THE CODES SHOULD BE CLEARED IF THE CAR THROWS ANYMORE CODES AFTER THIS THEN GO GET IT REPAIR, DO NOT CLEAR ANY NEW CODES BECAUSE THE SHOPS WILL USE A SCAN TOOL TO READ THE NEW CODES, THAT EASY, I HOPE I HELPED YOU WITH YOUR PROBLEM, THIS IS FROM bLEVINS AUTO REPAIR IN ALTURAS CA,,,, THANK YOU...

A C-23 code indicates that 27 key cycles ago, the headlamp switch input circuit was open - whatever that means.

Replace the speed sensor located on top of the differential housing of the rear end.

Bleed the longest line first, then progressively shorter lines. Make sure you are using the correct technique in bleeding--be sure the master cylinder is always full, then pump the pedal several times in quick succession and hold pressure while your assistant opens the bleeder valve slowly and lets it drain until your foot is to the floor. Hold your foot until the bleeder is again closed, then repeat the process. Don't reuse the expelled fluid. Hope this helps!

check the speed sensor on the transmission,the wire could have been cut or the ground may have been attached to a bed bolt and it could have been overlooked.
