- VS Berlina
Hi all,
Bit of an issue with my 95 VS Berlina (Auto, V6). At times when I am driving around, as I pull up to stop, when I sit idling the engine surges. The revs don't change (at least not noticeably) but it is as if I am gently throttling on and off, on and off. If you don't keep the brakes held on realtively forceably, the car likes to do little 2 inch or so lurches forward.
Now, this only occurs SOMETIMES when I am driving, and this appears to be related to the times that my climate control panel will work or not. Sometimes, the climate control panel will not work (i.e pressing ANY or ALL of the buttons will not get a response, the LCD screen does not light up and the unit is completely dead). When the climate control panel will not work, this is when the car decides to surge as I idle, but if the climate control is working (doesn't matter if it is running or not, just as long as it is working) the car idles fine. When the panel is working, all functions, including fan speed, AC, demisting and temperature all work fine.
I was sort of thinking along the lines of this being some electrical problem, but not sure what. I can find no pattern as to when the climate control decides to work, it can be lights on or off (or high beam), stereo on or off, or any other number of variables that I can think of being different. Sometimes the climate control will work immediately when I start the car, other times it will kick in after 15 mins, other times it still won't be working after 2 hours. Could it be that a fuse or a relay is faulty, which is causing the issues with the climate control?
More importantly, regardless why the climate control panel works intermittently, why does this play with the throttle at idle?
I'm not sure where to start with this so any help is greatly apprecaited.
Cheers
