Well my gf has a 97 accord ex, she has had it for over 3months(bought from private seller) no problems. Well lately her battery has been dying, took it up to a shop where they told us the heater motor and control panel is staying on even tho the keys are not in the ignition, they checked starter,alternator,battery. They wont touch it cause of an aftermarket alarm/remote start. Took it to mickey shorre and they checked it and the remote start checked out ok.
They checked some of the fuses and we even pulled a couple for the heater but the lights stayed on, they even cut a yellow and black wire under the dash thats for the heater control i believe and it still stayed on.

We drove it down the street after they couldnt find anything and parked it and the lights went off, got home lights stayed off. checked on it 2 hours later...they were back on and draining the battery.

Any ideas where to start? Could it be a bad on/off switch for the heater or a bad control panel(panel that changes where the air comes out of)?

I have no clue where to start with it, hopefully this made some sense to someone or maybe someone ran into the same issue somehow.

Thanks for any help.

 

For now, pull the no. 8 fuse (7.5A) fuse located in the under dash fuse/relay box.

The black/yellow wire in the circuit should have cut power.

As a test, with the no. 8 fuse in, pull the blower motor relay located in the under dash fuse/relay box and see if there is any difference.

 

pulled the number 8 fuse and nothing, pulled blower motor relay and nothing. Also noticed that the low temp fan will turn on as well then stop and you can hear a slight busing noise(like if you put a light switch right between on and off)

 

I would have them check the ignition switch circuit.
