so this is quite a story i borrowed my mom my skoda on monday on which she came to me panicking that there was smoke coming out from the back, so she was driving with the back wiper on all day while it was sunny and dry so i assumed she burned the motor which i was okay with and then on wednesday she comes to mee again after borrowing car and says that now the front windows wont close (windows problem has been solved they can be closed with the key but only the window controller is broken here) back to main issue so after looking at the car with my friend we noticed that when the car enginge isnt even on the fan for the enginge turns on so we looked into fuse boxes and found one broken fuse the one that belonged to back wiper motor and he also told me to buy new relay 645 which is the main relay but after changing it to the exactly same one skoda approved relay the car wont start anymore so today he decided to take out comfort control module and change it to new one to see if they car will start at least now. so basically short story long the back wiper motor is fully out cause it was burned relay is changed to new one bad fuses were swapped but car still wont start and i cant figure out why there is nothign when you turn the key except light on dashboard and the engine fan turns on after 20 seconds.

What codes are stored - playing part replacement wont help other than making things worse?

 

Check battery voltage as if on its way out can cause random problems,

 

we did check battery and its sitting at solid 11.94

also when we plugged the computer it just showed a bunch of errors nothing that made sense

Such as?

abs system traction system pressure in tires and couple more but those are just few off my head

If that voltage was read in correct manner, at 11.94 volts the battery is less than 40% charged!

Strongly suggest getting battery tested and check alternator operation.

All those faults strongly suggest a failing battery or faulty ABS sensor.

That's not that solid....

Pretty flat really

would that perhaps cause the car to not even give single sound except the fan turning on like crazy?

It might 

I'd charge the battery at the very least

Cars a very sensitive to low voltage these days - I'd start with a new battery unless it's very nearly new!

...or at least get battery charged and tested.
