1994 348 AC code E4

After turning key/engine on "E4" message will appear in the air conditioning digital display. There is no cooling.

What does this "E4" code mean???
Thanks

It means your going to have to take out your climate control panel and dissaemble it. There is corrosion in the circuit board connections.

I am having problem with my 1992 348 a/c, which reads "E7"} after the a/c or air vents have been turned on for about 5 minutes. I wonder if the cure is the same as that for the "E4" posted 9/18/04. I would appreciate any help for this.

I would think that it is. Most of the time the problem can be traced back to a poor, or broken electrical connection.

My A/C display is out also after experiencing a burning smell from my vents with the A/C on. It came back on and then out permanently after a short while. Any idea's ?
