Passenger Window Autodrop when weather is Hot

[grdriver]

So im having the weirdest issue, I recently had this issue that whenever I park my car under the sun for a little while and it gets hot inside my passenger window does not autodrop and my car beeps twice when unlocking. When the weather is normal temps everything works fine.

Note. I have changed both microswitches and everything works fine, except for the only time when I leave the car parked under a hot sun.

Has anyone seen this before? Possible cause??

Thanks in advance

Two beeps indicate an alarm issue, get the fault codes read for a better insight in to the problem.

Problem is that it hasn't been really hot lately so the beeping does not occur. Has anyone else heard of this issue ?

As RFM said get the fault codes read - they will still be there whether there is beeping or not.
