My gf had subs put in her car not professionally months ago. I changed the speakers and amp added a switch to the switched wire since the amp was not turning off and the battery was dying, about a month later I changed the temp sensor. A few weeks later the gauges started jumping up and down dash lights stayed on radio turning off and on showing a symbol something like a broken key. So i disconnected the power to amp at the battery that didn't help. the guy who wired it originally looked at it and noticed a few fuses weren't pushed all the way in so he pushed them in and the guages started working when he reattached the amp he disconnected the ground to the battery when he put it back on the radio never came back on. no display on the screen what so ever checked the fuse pulled the switch wire it was pushed in with the radio fuse. pulled the ground off the battery for several minutes and reattached nothing. should add that the temp gauge also stopped working when the radio did and a few days ago it started working again. im thinking it has no power since the screen is displaying nothing but i don't know where to go from here

Most likely the wires rubbed together or wire grounded out. You could put an inline fuse in wire for safe precaution Replace switch and run new wire and should be good to go.

Sir,
It's probably the brake lights that are staying on, check again, if the brake lights are staying on the brake light switch needs to be replaced. The reason I believe it's the brake lights is that they will turn on even with the key off so make sure which lights are staying on.

SOURCE: i have changed the relays and fuses checked
replace coolant sensor connector?if so can u get a thermo lazer gun to check the block temp? this will tell u if the gauge is incorect,,,go ahead a bleed all the air out of cooling system and see if that does the trick

Try under the dash, attached to colum is a switch that the rod goes into from your ignition key switch, that may need to be adjusted tword your steering wheel just a touch, they go out of alignmnet from time to time

if you got a spark when you touch it to the side (which is the ground) the wire is a power source that should go to the terminal at the back of the lighter. there is no relay for this circuit so change the new fuse it's blown and check for burnt wires.
