hi, I have a renault megane II 2008 sedan that was given to me by my brother. When i got the car he told me that the instrument does not work and the start does not start. since i am a bit technical i started troubleshooting the vehicle. the cluster is still not displaying, the watch was not displaying but now does after i have removed engine fusebox, ecu, bsi under dash, and made sure that all fuses are not blown and also relays are still ok. what i have realized is the card reader & start button does not have power when i use my test light. the car does not start & the warning light on the instrument panel flashes all the time. sometimes the windows works somtimes they don't. the card locks some doors not all. your help will be highly appreciated.
