Good morning I have an 05 Santa Fe 3.5 l it started not starting so I was told it was the battery I replaced that ran good for a week on the battery then it started not starting again was able to jump it had alternator check starter checked and put a new battery in- put new battery terminals in also, every time I try to start it or jump it the AC comes on or the defrost specifically and then everything else goes bad I was told that condenser is bad and that it can be bypass could it be causing all these problems ?please help!!

 

The only way a condenser can produce an electrical problem would be if it causes certain pressure switches to not work correctly and therefore the compressor would not work or might stay energized all the time.

Whenever defrost is selected on most systems the A/C compressor is activated also.
When all functions are off nothing should be activated.
At this point it needs to be determined what is staying on (energized) when nothing is selected,,,,,,,,,,,,,,,,,,if,,,,,,,,,,, that is what is happening.
