A/C cold, then hot, than cold???
1989, 260E, 294,000Km
Since a few weeks my A/C acts strangely.
It has been performing very well in the heat of the summer (near 100deg. at time) keeping the car nice and cool.
Now, driving at highway speed or standing still in traffic .the A/C would switch to full heat for 30 to 60 sec, then back to A/C (full blast) to cool it down. it could cycle this way once or twice an hour.
Any idea? Thanks
