electrical help please

i have a 95 escort and i tried to put in a cd player and now when i shut the car off the heater stays on and the daytime running lights unless i pull the ebrake. also the dash lights wont dim. ive pulled the cd player and seperated all the wires and still the same. any help would be appreciated.

thx

Update....... ok I installled the stereo correctly, checked and changed all fuses, made sure stereo was connected directly to the battery. no exposed wires. The heater is still running when i turn off the car, and the running lights stay on still unless i pull the ebrake( the key is out of the ignition the whole time) and now i cannot dim my interior lights. is it possible that i shorted something in the process of hooking up the stereo?????? HELP PLEASE. what do u change or fix when your dimmer is messed?????? HELP

It's sunny out, and the bear's are fluffy. Just how fluffy...remains to be seen.

u all suck
