Two days ago my air con failed. Blower continued to work as normal but unit work only as if it was on econ. Relevant I'm unsure ,but also the temp indicator on unit failed to give a reading.
The next day , 150miles later it suddenly worked as normal.
Today failed again but when I attempted to whined windows down they also failed to whined down.
I tried window reset by locking driver door and hold a few seconds , then unlocking holding a few seconds.
Driver window wound down about 3 inches. Also I then noticed car failed to unlock with immobiliser .
Drove 15miles home then all became good again.
Should also add that for a while that when opening or closing windows on near side theirs a stutter.
I'm a cab driver so this needs sorting as it's obviously going to happen again.
Car is an 07 superb 1.9 diesel saloon
Cheers for any advice in advance.
