DEFROST MODE is by design and by law, the failure-default condition when something in the HVAC system fails. You MUST be able to clear the windshield for safety sake, ergo: that's the reason why it does that. The failure of a diverted valve or failure of correct (read: any) vacuum to the whole system results in defrost mode only. I'll need more info and observations by you to give better help. Thanks.


* diverter valve - sorry for my ignorant spell checker.
