2000 V70R AC/fan question

So i recently purchased said vehichle, the AC worked fine and the slider allowed me to either choose auto or whichever fan speed I desired. As of the other day though, when I start the car the AC "off" button and the air "thru cabin" start to blink and now when I slide the fan selector to either on or auto, the fan will come on for a second and then stop and the lights on those same buttons will start blinking.

Ive been told that the number of blinks will tell me what issue the system is having, can anyone tell me what the amount of blinks mean?

If this is an issue that is common that I should search for on the forums, please direct me to where, as in browsing from my iPhone and the search function leaves something to be desired.

The 20 seconds of blinkies just tells you that the ECC is unhappy.

The module has to be interrogated by the right kind of scanning

tool to tell you what's specifically wrong.

Usually means the fan is drawing too much current and system shuts it down, could be the fan itself or the blower resistor . Before buying new parts you can take out the resistor to check for corrosion on the resistor board that could be shorting it out and clean it up, also can try to clean and lube the blower motor.

Ok so I have the blower motor out as well as the blower fan resistor and it's opened so the board is exposed. I don't see any corrosion on the board or anything. The blower itself is like in a pressed case so I can only get open access to one bearing. Sup with that?
