Hello lica_abel, thanks for your question in the community.
Your described fault Code means: E704 IHKA: K-CAN wiring fault
If you have a wiring diagram from your car, you should check the CAN Bus from your climate Control unit.
But you can still test it with a hard reset, means: disconnect and connect the battery after a few minutes.
Maybe the Control Units could reinitialize and the fault is erased. Thats the simpliest thing.
When the fault Code be Patient, so you have to check the Bus and the Control Units Plug.
But sometimes the fault could comes from the Control unit self..
