Took out my heater now the heat won't turn off Sign In

While trying to fix my radio I took off the knee panel and removed the radio along with the heating unit. Well now that I've plugged the heater back in whenever I turn on my car the fans and heat blow as if it were on high but my heater won't even turn on.

What does that mean. Are you having a blower problem, an air direction problem or a temperature problem?

It's a 1993 Chrysler concord 3.5L. The heater unit (the thing that changes temperature, adjusts the heat/fans) Is not turning on it's plugged back in how it was but it's not turning on anymore and when I turn the car on it starts blowing all the fans and heat on high and I can't turn it off or even adjust it.

You're still not clear on what is happening. First you say the whole control head is dead and then you say you turned the fan on. What works and what doesn't?

I didn't turn anything on or off. I took the whole control unit out and unplugged it. Now whenever I turn on my car the fans blow on high even though it's not plugged in. I plugged it back in and it doesn't work anymore and it still blows on high.

OK, that is a fan issue. What about everything else? Can you switch the air direction from center vent to defrost or floor? Can you turn the A/C compressor on and off?
Can you change the temp?
Is this an auto temp control system,?

OK, it looks like again you have dived into something that you shouldn't have. You aren't qualified for most of the stuff you are attempting. I can't help you.

There is nothing you can say to help me? Obviously taking it to a mechanic would fix it but that will cost alot of money and the whole point of me trying to fix it is to learn how to.

Just keep taking things apart. You'll eventually make some mechanic very rich.

Did you disconnect the battery before you unplugged the control panel? The BCM is what controls the fan and all that garbage. BCM is probably wigging out because you unplugged the control panel without disconnecting the battery.

Try this:

Turn off the ignition. Put the keys in your pocket. Disconnect the negative cable from the battery. Make sure everything on the back of the panel is plugged in. Go inside and have a coke or beer. Come back out and reconnect the battery. Take the keys out of your pocket. Turn the ignition on. See if your problem is gone.

I did not remove the negative before unplugging it. I just disconnected it, waited about 15 minutes then reconnected it and turned it on. It is still doing the same thing and not working though.

Check fuse #6 10amp in the junction block. What were you doing to the radio? Be detailed, please.

I was trying to find a short because my radio comes on but no sound comes out of the speakers. All I did was unplug it.

Thanks^^^ I did try unhooking the negative but that didn't work. However I did fix it and the heater is back to normal. The radio still doesn't work unfortunately.
