1982 300D Auto Climate Control on fritz
The ACC in our car didn't work when we got it. The seller said it was probably a short. We replaced the fuse and it shorted within 24 hours. Any pointers on where to start? Does it sound like a short somewhere in the system or something else?
Thanks in advance! |

Are you defining "shorted" as a blown fuse? A couple of things come to mind that could cause this.........blower motor.........aux. water pump.........defective ACC controller. What were your settings? A/C or Heat?

Blowing a fuse doesn't neccesarily mean that you have a short (though you may), just that you're drawing too much current. A "short circuit" happens when a circuit is grounded before current reaches its intended load (like a bulb or motor), such as when a wire's insulation rubs through and the wire touches metal (ground). Electricity takes the path of least resistance, so current goes to the new ground instead of to the load. This can cause a fuse to blow if the "new" circuit draws too much current. FYI, if a wire is cut all the way through or disconnected, thereby preventing the flow of current, that is referred to as an "open circuit".
Which fuse are you blowing? Blower motors are notorious for drawing too much current as they die, causing the fuse to blow.

Hmm, maybe it was the blower motor. We had the AC on and it blowing pretty hard and then all of a sudden there was a burning smell and then it stopped working.
I guess we are also going to have to open it up and take a look since there was no air moving from the center vents and I read about the hosing falling apart. |

Center vents not blowing is probably a result of a bad vacuum pod. It's not the easiest pod to access.
