I'm hoping the internal fan systems on LX Delta's and integrale's are fairly similar so maybe you guys can help me out... Basically, when you turn the cabin fan on you can hear it working, but very little air is blown from the vents, even on full power. I've found that when I remove the tube labelled 1 in the above photo's, then air is blown into the cabin as it should be. The white plastic elements attatched to the back of the cylinder the tube was removed from also change position. If the engine isn't running, then you can re-attatch the tube and the fan will continue to work. However, the minute you start the engine the plastic parts go back to their previous positions and the air stops blowing. The tube coming from the other side of 1 travels along the bulkhead to point 2, which I'm assuming is some sort of vacuum, and a pipe from that connects it to the engine block at 3.
The fan is working so I don't think it's a fuse or anything - does anyone here know what could be causing this?
Also, recently the engine has begun running rather poorly. It won't stay at constant revs. If I were to try to maintain a constant 2000 revs then it will oscillate between 1600 and 2000 revs, this leads to the car being jumpy when you're trying to maintain a constant speed, it also doesn't seem to be accelerating as smoothly as it should, with acceleration dipping and rising in time with the rev oscillations. The plugs are roughly 1 year old with about 10000 miles on them, as are the HT leads - a new distributor was fitted a few months ago. Again, any ideas or help would be greatly appreciated.
Finally, the dash electronics seem to have a mind of their own. The speedometer only works when it feels like it, and often seems to cut out or come on at the same time I press the brake pedal... Having said that, it will cut out or come on when I'm just cruising on a motorway. Could this be connected to a hissing noise which comes from behind the dash when the car is running? Also, could it be linked to the economy-meter not working all the time as well? Again, any help anyone can offer would be greatly appreciated! :D
