Ok so i have a couple of problems with my lexus is300 2005, i have noticed that every time it rain or i put my car thru a car wash that my stereo has no sound coming out of it, it turns on and all but no sound come from the speakers. Also when it rains my mpg and rpm gauges dont work and the signal light thats indicate i need an oil change turns on. After a couple of days the gauges start to work again and the oil change light turns off but the stereo problem is still there. Do you guys know of anything like a sensor or something that might be getting wet that might cause my cars electronics to act up? Thx for any help ahead of time..
