E-problems with Calibra

Hello first of all, have since last week a Calibra at home. Unfortunately he has a few electronic problems. 1. the passenger window lifter only works from time to time. But have also four switches, but have only two windows 🙂 2. the sliding roof does not work, engine runs however. 3. Lighting of the heating element is broken 4. The outside temperature indicator does not work, where is the sensor? And now a stupid question, but how do I set the clock at the on-board computer? a few questions, but it’s just a lot different than with my Audi. Thanks already in advance, and greets all Cali drivers. lg from ktn
