2003 Chevrolet Monte Carlo Electrical Problems

I keep rewriting this because for some reason it keeps timing out everytime I look for the video to attach. I brought the car to taska twice for underhood fire and ignition. No head gasket got fixed no spark plugs there is several issues water keeps getting in tires are rotted electrical problems and now head gasket is messed up because the hood wasn't put on till afterwards for the recall the ignition is still not fixed. Last time I drove it back it stalled out and smelled over heated

WHEN I GET IN THE CAR AT TIMES AND POUT KEY IN IGNITION, THERE IS ABSOLUTELY NOTHING. THE ELECTRICAL SYSTEM IS DEAD. I HAVE TO DISCONNECT THE NEGATIVE ON THE BATTERY FOR ABOUT 2 MINUTES TO GET IT TO WORK AGAIN. I ALSO EXPERIENCE FLASHING DOME LIGHT, BRAKE LIGHT ON, IGNITION BELL RINGING WITH NOTHING IN IT, ALSO INDICATORS ON DASH PANEL, SECURITY, BATTERY, DOOR OPEN, LOW FUEL, CHANGE OIL SOON, AND THEY WILL NOT STOP SHOWING UNTIL I DISCONNECT THE BATTERY AGAIN AND SET SYSTEM. I PUT A COMPETE NEW IGNITION IN IT, BOTH THE KEY PART AND THE IGNITION BLOCK AND I STILL HAVE THIS PROBLEM. I WAS TOLD BY CHEVROLET DEALER THAT THERE IS NO WAY TO BYPASS THE SECURITY IN THIS CAR BECAUSE THERE IS A CHIP IN THE STARTER THAT PREVENTS THIS. WHEN I GET OUT OF THE CAR AND PRESS THE LOCK ON THE KEY FOB REMOTE, THE HORN BLOWS AS AN INDICATOR THAT THE CAR IS LOCKED, BUT I CAN WALK OVER AND OPEN THE DOORS EVERY TIME. THE LOCK SYSTEM FOR THE DOORS IS NOT WORKING ELECTRICALLY EITHER. I AM AT ODDS AS TO WHAT TO DO WITH THIS PROBLEM BECAUSE BEFORE I SPEND MONEY TO FIX IT, I WOULD LIKE TO KNOW WHAT IS CAUSING IT FIRST. ALL THE DEALERS WANT AT LEAST $119.00 JUST TO DIAGNOSE THE PROBLEM. AND, I FEEL THAT IF THEY WANT MY SERVICE THEY COULD GIVE ME A BREAK AND THEN FIX MY PROBLEM. THAT WOULD BRING E BACK AGAIN AND AGAIN. IF YOU CAN, PLEASE HELP ME HERE. THE CHEVY DEALER SAID GM DOESN'T EVEN HAVE A FIX FOR THIS ISSUE EACH AND EVERY TIME THIS HAS HAPPENED, THE VEHICLE WAS STATIONARY AND NOT RUNNING INITIALLY. INGERSOL CHEVROLET SAYS THERE ARE NO RECALLS ON THE IGNITION SYSTEM FOR MY 2003 MONTE CARLO SS 3800, 3.8 VEHICLE.

WHILE OPERATING MY VEHICLE AT VARIOUS SPEEDS MY VEHICLE APPEARED TO LOSE POWER AT THE DASH. CERTAIN DASH INSTRUMENTATION AND THE AC BLOWER MOTOR WOULD JUST STOP OPERATING, FOR NO APPARENT REASON. THE VEHICLE WAS TAKEN TO A DEALER WHERE THEIR FIRST DIAGNOSIS WAS A BAD AC BLOWER MOTOR THAT WAS CAUSING THE ISSUES AS MENTIONED. THE DEALER CHARGED $365 FOR A NEW AC BLOWER MOTOR TO BE INSTALLED. AFTER THE NEW AC BLOWER MOTOR WAS INSTALLED AND WITHIN THE FIRST 5 MILES AFTER LEAVING THE DEALERSHIP, THE BRAND NEW AC BLOWER MOTOR STOPPED WORKING. VEHICLE WAS TAKEN BACK TO THE DEALERSHIP, WHERE THEY NOW DETERMINED THAT IT WAS A FAULTY IGNITION SWITCH THAT NEEDED TO BE REPLACED AND THAT IT WAS NOT THE BLOWER MOTOR AS PREVIOUSLY DIAGNOSED. I ASKED ABOUT THE RECENT RECALL ON IGNITION SWITCHES AND I WAS INFORMED THAT ONLY THE IGNITION KEY IS COVERED UNDER THE RECALL AND NOT THE IGNITION SWITCH. A NEW IGNITION SWITCH WAS INSTALLED AND NOW EVERYTHING APPEARS TO BE OK. I CONTACTED THE DEALERSHIP IN AN ATTEMPT TO GET MY MONEY BACK FOR THE COST OF INSTALLING AN AC BLOWER MOTOR THAT DIDN'T NEED TO GET REPLACED. THE DEALER REFUSES TO REIMBURSE ME THE $365 FOR WHAT I HAD PAID FOR THE AC BLOWER MOTOR. THEY CLAIM THAT THE IGNITION SWITCH IS NOT COVERED UNDER ANY RECALL. I AM CLAIMING THAT THE IGNITION KEY SWITCH WAS DAMAGED AND ULTIMATELY FAILED AS A DIRECT RESULT OF THE CURRENT RECALL KEY ISSUES FOR MY MODEL AND YEAR VEHICLE. I SHOULD BE REIMBURSED THE $365 THAT I PAID FOR AN AC BLOWER MOTOR THAT I REALLY DIDN'T NEED. THE RECALL SHOULD NOT JUST COVER THE IGNITION KEY, IT SHOULD ALSO INCLUDE THE IGNITION SWITCH IF IT PROVES TO BE DEFECTIVE AND/OR HAS BEEN COMPROMISED IN ANY WAY BY THE IGNITION KEY ITSELF. *TR

I BELIVE THIS IGNITION SWITCH CAUSED MY ACCIDENT. *TR
