Hi, it's just getting summer here.

I had a bad smell inside car. So i removed everything to try find the Cabin filter.

But mine doesn't have any filter.

Anyway, i have photos of how dirty was my evaporator.

See the disassebly:

removed engine board, and then both wipers, and then the plastic protective , between front glass and motor. There was a lot dirty inside.

then goes from inside, removed may things but very easy.

The yellow is the passenger Airbag cable connection.

I removed and cleaned the round air-motor , see the empty round hole?

The ECU on the side

The cental Relay, click-click-click problem, it's always the cause, don't fool yourself.

Camera inside through round hole, photos of the evaporator.

Blower resistor, what cause 4 scale air blower working.

quality of everything is top. All electrics are installed perfect, believe me.

I just showed you the inner world of santamo.

the bird like is a glue, in which they installed the AC temp sensor, to know when the AC evaporator freezes, and to stop AC compressor, until it u-freezes.

The blower resistor is the latest photo of my post, a black rectangular, with 1 fuse with 4 cables.

it has 2 inox screw holding it in place.

I hope i answered your question.

Please, can you explain me what you are doing with the central relay?
