All warning lights on dash come on and all electrics stop working

I suggest you try one of those instant download manuals. My nephew bought one for me when my car broke and we could fix it all by ourselves with the manual costing $10. This website reliable-store.com is very good for this.
?Try it.

I would try cleaning the throttle valve body and also the automatic idle speed control valve mounted to the throttle body, this is a common symptom of a dirty throttle valve and idle speed control valve. Use a product called "CRC" Throttle valve cleaner, run the engine and spray it into the air intake of the engine with the supply hose removed, hold the throttle up while you do this as it will try to stall, use up about half the can and then shut it down and disconnect the battery NEGATIVE cable for 5 min's to reset the system learned strategy, drive it for a few days and see if this corrects the problem.

Check te fuel pressure regulator

1. So the car was running normally and then on one occasion you put in the key to start it and all the warning lights flash up on the dash and the starter motor will not turn the engine over. Is that correct.

2. When you last drove the car were any warning lights appearing on the dash.such as check engine warning, engine overheating, electrical charging warnings etc.\

3. Has any work been carried out on the car recently.

4. How old is the battery in the car.

You probably aren't going to believe this but the first thing to do is remove and clean up your battery posts and terminals. A momentary disconnect will drive the dash nuts!
Easy to do and hopefully repairs it.

I work for a dodge chrysler jeep dealership,we replace alot of regulators in grand cherokee's,have replaced a few window switches,your dash light problem is more than likely in the head light switch,try working the brightness control and see if that helps

Auto warning light comes on but goes off when car stopped and restarted. Temp also goes higher

Speed Sensitive Power Steering
(SSPS) Warning Light
If your vehicle has Speed Sensitive Power
Steering (SSPS), this warning light will
come on briefly when you turn the ignition
to ON as a check to show you the bulb is
working.
Then it should go out after a few seconds.
If the warning light does not come on, have
it fixed so it will be able to warn you if there
is a problem.
If the warning light stays on, or comes on
while you are driving, the SSPS system
may not be working. If this happens, see
your SUZUKI dealer for service.

thats a cold weather warning,its getting to freezing point !!

There is only one wire to the emergecy brake, when it is grounded it completes the circuit to the light.
