My heaters on high & can't be turned off and the radio won't come on.

your car either takes a group 58 or 59..whatever the motorcraft battery that (BLANK) took out,i would have put the same back in it,or just looked in the owners manual.who took the old battery out,and who put the new one in??? the blower motor resistor is more than likely burnt,it defaults the blower motor to high and or wont turn off when it's burnt..the radio might need you to enter a code,not real sure on that vehicle,but you can find out by reading your owners manual.and,NO,the factory ain't gonna be making you a part(one part)..everything should have been turned off before disconnecting the battery.the battery is not the problem unless it was hooked up backwards.and YES,find you a good mechanic,because the one you have now has a few lights out! what part is the mechanic looking for? why didn't you just go to Autozone,they install vehicle batteries for FREE..
