What else could cause the issue when one side is blowing hot air while the setting for both sides is equal? DATC? Heater Core? Something else under the dash? DCCV already changed. Especially it gets hotter on one side when accelerating. while sitting still the difference is not so noticable. Car is '00 LS V8. Hope someone will help with some suggestions (except visit dealer, because here in Latvia there are no Lincoln dealers and LS is quite rare here).
