K_Watson 1998 Prizm 3sp 127,000 milesThis is a stumper. Car ran fine all morning while running my errands... It's been fine for 7 year, besides A/C comp. and a starter (both fixed)I stop at goodwill for a 1/2 hour and come back out and it stalled when I tried to put it in gear to leave.If you start the car the tach jumps around for a second and the brake light illuminates, but the handle is down and the fluid is clean and full, then it will sometimes quit (not die, just shut down as if the key was turned off) and the small black relay on the lower drivers side relay panel will go crazy.If it does run it runs 90%, there's a little something off, a little variation in RPM that is not normal for the car before today, and is seen in the video... If you give it gas it will run fairly smooth. one time today it reved up and down on it's own while gas was held, but just that once.The weird parts...If the car is off and the key is out and you pull the turn signal lever to passing lights, one of the radiator fans comes on and stays on until you turn the key to "on" and then off. This is repeatable.The bright indicator light and turn signal indicators are dimly lit - this is every timeThe BRAKE light is on when running, yet brake is off - this is every timeIf you turn on the a/c, the engine RMP rises and compressor partly engages but doesn't have enough pull on the clutch to turn the compressor - this is repeatableIf you turn the blower up to 3 or max, even with the A/C off, the car quits - this is repeatableI know what you're thinking... but it's not the A/C, it's off in the video.If you put it in gear it quits. - this was repeatable, but I was able to move it a few feet one time I tried.If you turn on a turn signal, it and the BRAKE flashes fast and the car quitsWipers and sprayer work fine, no effect on carIf you turn on the brights, they don't come onIt will run happy for a bit then quitSome times it will just run happily until you turn it off, but it you do anything listed above it quits. This is repaetableI disconnected everything i have added like the remote starter, but it still acts up.WHAT I'VE DONE TO THE CARAir Conditioner - 2009 - works fineRemote starter - 2009 - worked this winter lost fob - wiring looks fine - now disconnectedStereo - 2010 - WorksLarger 34R AGM battery -2011 - Tested Good last weekSubs and amp for front stage 2010 & 2011 - WorksBIG 3 all in 4 gauge - 2011 - soldered terminals, amplifier, additional alternator power wire, and body to engine and engine to ground wires - clean tight, no corrosion or rustdriving lights - april 2013 - worksFull cluster and Ambiant Air Temp Sensor from Corolla with original Prizm Speedo / ODO - July 2013 - works*** The car was torn apart to diagnose, it was whole when this started. *** FISH?
