hi all, i'm pretty new here so any help you guys can give would be very valuable, i have a 2005 IS250 SE-L manual, i recently replaced the digitizer as the old one was dead, its been working fine since install, but over the past couple of weeks it only responds when it chooses too, my miss's read that heat can affect them, so as we've had these couple weeks of hot weather i was wondering if anyone else has had the same or similar problems and what you were able to do to solve it, cheers for any help guys :)
