instrument cluster malfunction
from 2 weeks i was in a car wash,when i finished washing my jeep,started the engine,it started normally but all the gauges like fuel indicator,rpm everything was going up and down randomly it lasted for 1 minute than everything became normal,but the check engine light that was on turned off(the code was p0455 evap system..)i drove it normally for 3 weeks(the check engine turned on again after 2 days same code p0455),than today i went to the gas station,when i tried to start the engine suddenly the gauges did the same thing but this time the engine didn't start,or start and turn off immediately,after 6 tries the engine started normally the gauges get back to normal but also the check engine light turned off,and i was using it for all the day and everything is normal now!!!
(P.S.:i don't know if this may caused this malfunction but from maybe 5 weeks the driver door panel was not working(power windows button,lock/unlock doors...)i've found that the red wire(+12v)was broken between the door and the body,i reconnected it isolate it using tape and mounted back the rubber between the door and the body)
i can't find what the problem,maybe it's a wire shortening and causing the pcm to reset i'm really confused...i'll be thankful any help or tips
