Hello everyone,
Firstly, i want to apologize for my not so good english.
I am a proud owner of one classic beauty - W124 1990 200 E model.
From about a month I have strange problem with fan speed of my climate control.
So the problem is expressed in:
When i start the car (doesnt matter if the car got to working temperature or not) my fan speed is very low. The problem occurs only when it is cold outside, so basically when the climate should heat up the interior. The air from the heating vents is very hot, only the fan speed isnt blowing with correct speed.
The problem doesnt occurs when i change temperature with temp. wheel to cold. In cool mode the fan speed gets high and it blowing on its maximum.
* Just to mention - I have made my own fan speed regulator, but the problem is not in it, because before experiencing the problem my fan speed worked perfect.
I measured control voltage to my fan speed regulator and it is on its minimum - 1.80 V, but I think it should be aroung 4.5-4.7 V until the interior temp. gets to temp. which is selected by the temp. wheel.
So control voltage is sent to fan speed regulator by CCU, on the basis of which measurements?
I think it is possible to have a faulty temp. sensor.
Does anyone experienced such issue?
Thank you in advance!
