I walk you through replacement of the front heater core on a 2000... I just finished replacing the fuel pump and sending unit on my2000 Olds ..

There is a control module.It's usually under the dash around the steering column.I would'nt be too concerned about replacing it based on the age of the vehicle

You should check out www.reliable-store.com they have info on repair, service, wiring
diagram, electrical diagram, fuse diagram, troubleshooting, PCV, owner's/service/repair/parts manual, fault codes, error codes, etc everything on all vehicles. must check it out

Could be a problem in the headlight switch. Can you make the dash lights bright-dim ?

In order for the heater core to be changed out, I'm pretty sure the dash has to come out, and there are many many wires that he could have hit or pinched that would cause this. It's hard and time consuming to trace down the wire that could be the culprit. My suggestion is to take it back to him and let them figure it out on their time and money.

if you cannot reach the light panel from under the dash by laying on yer back with the aid of a flashlight then,.....there are screws underneath the dash itself and this is somewhat moderate as you'll need to find all the screws and remove them to allow the instrument cluster to drop down and tilt forwards to access it that way ...but I would try the first method if it were me.......hope this helps you.

So, this is not a 2000 Hyundai Sonata? I used to own a 2000 Honda Civic and I believe those lights get power from a fuse inside the fuse/relay panel located on the driver's side under the dash. Check all your fuses. If all fuses are good, you've got a wiring problem - check for power & ground at each bulb. Obviously, if you don't have power to them, it's a power distribution/wiring issue. If you do have power to them but no ground, it's still a wiring issue.

Your alternator may be going bad. Test your battery while it is running with a voltmeter. It should be above 13.0 volts. I would check that first.

R u sure u tested it correctly? There will be a 30 amp fuse usually associated with the blower motor however u need to look at the motor connections with a meter set to ac. These newer cars use a pwm type drive which is a pulsating dc voltage similiar to ac and should vary in amplitude as u turn ur control for speed. If u have that then ur motor is bad and has to be replaced.

Disconnect Car Battery
I replaced the ignition switch in my wifes 2000 intrigue. (ignition mounted in front dash). I had to take off the knee bump trim and the trim around the instrument housing and remove the instrument cluster. Leave it connected and just lay it on the dash. You also need to remove the radio to get to one of the screws that hold the ignition switch module. Once you get that loose you can pull it out so you can disconnect the wires going to it.
If you need to replace the ignition module insert the key and turn to accessories, there is a small metal button to push in, then your key and the lock part will fall out to install into your knew ignition module. At that time you can also remove the cruise control cable.
I am not a mechanic and the whole process only took me an hour or so.
I replaced my ignition module to fix the heater and AC operation. It also fixed the cruise control that hadn't worked for a year.
