99 chevy blazer some dummy lites and other stuff went out
When i parked my vehicle everything was working. When i started it the next day with a full tank,it said tank was below empty,the temperature gauge is also not working,my battery lite is on,but the dummy gauge is working and looks fine...my lights for the 4wd buttons went out as well as the one that shows me what gear i am in. Also my heater is now stuck on hot even if i put it all the way to cold,what the heck could do all this? I recently had my dash pulled out,could this possibly be why?

You may have a bad revers solenoid. Check the fuse and look for any of the fuse to be bad like the transmission fuse. Best thing to do is get the blazer scanned at Auto Zone free of charge for any DTC codes that may be affecting your transmission's performance. Try this, place the ignition to the run position and pull the ECM(BATT) fuse out for 30 seconds and then place it back in. Start the Blazer, it may stall but let it. Just start it again the ECM is just relearning the engine and transmission, let it idle for 1 min and then go for a test drive. This should reset everything in the truck's ECM like the day it was first started and any DTC code will be new and active. Do not add any additives like lucas transmission fluid repair, that will just make it worst. Any additive that may the transmission thicker will make the fluid retention more making the shift solenoid stick causing shift conflicts. Good luck and keep me posted. No revers is ether a bad solenoid, bad PCM signal, or broken sun gear.
If you plan on doing alot of of your own work on your car, its best to go to the parts store and purchase a manual. The manual will have a full diagram of the engine. It will have everything that is to know about your vehicle in it. If they dont have one in stock they can probably get in the next day.
Air/fuel/spark. check the 3, and then do a dummy test. I know , im not insulting you, but my dakota wont start if my gascap isnt screwed down all the way, it throws a sensor and it wont start. So just do all the dummy stuff you know has to be done to start it, put it in park, close all the doors, stuff like that, never know, could be something simple. if not, as above, Air/fuel/spark. need all 3 to start an engine.
