Underneath the glove compartment on the passenger side is a cover which must come off,2 plastic screws holding this cover.Underneath you will find a 5 pin connector[big plug] connected to a white connector in the blower fan housing.This is called the fan resistor which controls the blower fan speed.Unclip the resistor out the housing and renew.Your problems should be solved..regards

you can order one from dealership what is it that you are looking for. good chance i might know.

I clipped this from my Mitchell manual:

on top of brake pedal there should be a switch. wire going on it, diconect plug turn and remove switch fit new one and reconnect plug

judging by the amount of km it has done i would say the rpm drive is faulty, this measures the amount of rotation in the camshaft and shows the "revolutions per minute". when this goes faulty it stops the read out on the dial, so you want to be looking for a device that measures the speed that the engine is turning, if you have, replace it and it should solve the problem

there will be a screw behind the rubber this holds the handle in., if the door has not been used much, greaseing the mechanism may solve this

That sounds about right, the idle speed may not even be manually settable due to emissions regulations.
I know for sure you can't adjust the idle mixture anymore; that is determined by sensors and the on-board computer.
There may still be adjustments on some cars but they are often sealed with lead to avoid tinkering.
