Mine did this once. The entire AC control panel was dead as if it was disconnected.
I made it start work again by reseating the AC fuse in the fuse box under the back seat.
Go figure...
If the noise you are referring to is coming from the front, it may be the guy assembly. Easy way to check, lift the front of the car and rotate each wheel by had, if you hear the grinding, your huh assembly needs replacing. Local automotive parts store usually have them in stock for around $104 but if you have a few days to wait, Rock Auto.com can get them to you in a few days for 1/2 the price.
It like this the battery supply's the power to the starting motor to crank the engine over that is a good point to start checking .
However the ignition switch opens the circuit like a light switch on your wall open closed.
Now you need to figure out what works when the key switch is in run position do you have major power windows seats door locks if so the battery is fine .If not you need to take a good look at the battery TEST IT if that's good then look at the fuse box any fuse that would stop power flow would a 20 to 30 amps yellow or green the # will be on the back of it
Next you need look at main connections and grounds like from the battery to the starter and solenoid yank on the cable to the starter from the battery check your main ground cables fusible links look for corrosion.
Then you can start thinking about what you need to take APART.

I recently
tried the DIY service and repair manuals from a website and it actually helped me repair transmission problem in my jcb 3cx site-master. it wont move forward or reverse, engine is good both solenoids for forward and reverse work.
I don't have much technical knowledge but I just followed it step-wise, and works perfect! got it from www.reliable-store.comAll the best
You are all incorrect with diagnosis. And there is no button hokd calibration, stop it. Read on. So easy a caveman could do it. 1.5 hr job only removing glass.
(Inside vehicle)Remove the 4 hex screws that attach the glass to the rail guides and remove the glass panel. This will also allow for manual movement of rails. The glass is adjustable(hight only) so mind the position when removing the screws. . Hold the glass like a pizza pan for it will slide down as u loosen each screw, remove the screws then lift upward and rest glass on roof. Removing the glass will give a good view of both guide rail and concting arms. The crunch you heard was one of the connecting arms plastic rail guide tips breaking. Picture a catamaran for a moment. The pontoons are the plastic pieces that slide fore and aft inside the rail and keep everything aligned. It will be the outside(pontoon) guide piece that failed. When that broke, a lot of play was allowed and began binding. Bless the poor folks who bought a whole new unit for nothing. I fabricated two pieces from the plugs off an older dell power supply. The plugs were the exact same length as the factory guides and even beveled ends. I only had to cut the plugs in half long ways and then install on the slider. Even the holes that are already in the plugs fit the stud (pivot stud that the pontoon slides onto) the guide. Sunroof will not vent if any of the pontoons are damaged. When venting, theses guides(pontoons) pivot upward through a slot on the top side of rail slot and rest on the rail so not to close by wind. Hope this helps. Any questions eamail me at dubyadubyadubya dot maxrevadvisors at g mail.
I suggest you get one of those manuals people get nowadays to do it yourself.. My nephew use it to repair my car and it's totally repaired now. Here's the website he bought it from.

Have the various systems scanned and see if they show a fault code, I suspect they will. As far as the gauges go that sounds like the rebuilder screwed up.
Any code's stored in the ABS ? The VSS - vehicle speed sensor is an input to the PCM - engine computer . The PCM sends this info. on the class 2 serial data network to the instrument cluster . The Instrument cluster has a microprocessor that deciphers all relevant data , speedometer , tach , fuel level , temp. etc... an through the use of stepper motors controls the gauges . Do you know what a module serial data network is ? Do you know what computer controlled systems on a automobile are ? The ABS - anti lock brakes need speed info. also , as does the transmission for shifting point's . The parking brake light is more then just to let you know the parking brake is set . ABS problems , low fluid level in the master cylinder will also turn on this light . Having the vehicle hooked up to a professional type scanner should be the first step in the diagnostic process . Check DTC'S , view sensor data parameters .
Engine Coolant Temperature Gage
The IPC displays the engine coolant temperature as determined by the PCM. The IPC receives a class 2 message from the PCM indicating the engine coolant temperature. The engine coolant temperature gage defaults to 100°F (40°C) or below if:
• The PCM detects a malfunction in the engine coolant temperature sensor circuit.
• The IPC detects a loss of class 2 communications with the PCM.
PRNDL Display
The IPC displays the selected gear position as determined by the PCM. The IPC receives a class 2 message from the PCM indicating the gear position. The PRNDL displays blank if:
• The PCM detects a malfunction in the transmission range switch circuit.
• The IPC receives a class 2 message indicating the park position and the column park switch indicates a position other than park such as an open input.
• The IPC detects a loss of class 2 communications with the PCM.
Speedometer
The IPC displays the vehicle speed based on the information from the PCM. The PCM converts the data from the vehicle speed sensor to a 4000 pulses/mile signal. The IPC uses the vehicle speed signal circuit from the PCM in order to calculate the vehicle speed. The speedometer defaults to 0 km/h (0 mph) if a malfunction in the vehicle speed signal circuit exists.
Tachometer
The IPC displays the engine speed based on the information from the PCM. The PCM converts the data from the engine speed sensor to a 2 pulses/engine revolution signal. The IPC uses the engine speed signal circuit from the PCM in order to calculate the engine speed. The tachometer defaults to 0 rpm if a malfunction in the engine speed signal circuit exists.
You could have any one of a number of different thing's causing your problem . Hooking up a scanner probably would point to the gremlin .

Oh is the "A" Frame OK, also the door frame where the hinges are your looking for damage distortion creases etc.
As the body guys say a dent is fixed by reversing how it happened, so to me this will be a body shop job. Ask a friend in the know to have a quick look see.

There is no dedicated fuse for speedometer only. There is voltage and ground for the instrument cluster.
The vehicle speed sensor sends a signal to pcm concerning speed then the pcm sends signal to instrument cluster for speedometer.
causes for the injector/s failure are
wiring
injector
ECM
as all injectors stopped working at once , check the connection on the ECM
find a known good ECM and substitute it as it may be an ECM failure
check for a failed fuse for the ECM
If the outer bearings can go bad, so can an inner bearing. A close visual inspection will usually reveal a bad bearing or you can feel it when you spin the bearing. You could check the gear grease in the rear end. Bearings in there can go bad.
