if it is an after market deck you must have the dash wires not hooked up behind the deck, and for the fuse replace it....
Short in the wiring, and it is probably the door light switch.
When you were replacing the cd player you might have sparked a wire causing the dash light fuse to blow. Check the gas light fuse in the fuse box.
you need a new blower motor resistor
check and see if the headlights flash and the secuity light comes on and goes off. that is what mine did. had to get the BCM replaced and reprogrammed.
radio broke see car dealer
because you hooked into the lights ground I bet usually you blow the fuse everytime you turn on the lights check your radio ground
probably the resistor pack on the evaporator case.
There must be a short in the system somewhere that causes the fuse to blow.
More than likely the blower motor speed resistor burned out.
i put ad battery cable on wrong and it blow sum of da fuses were can i slove this problem
Short in the wiring or the radio itself.
Engine "blow-by" excessive engine wear - bad piston ring
