Hi
I am new here and would like to say hi to all also see if anyone out there can help.
I have just bought a MKIII GTi 2l 16v on a P plate 1996, the previous lady that owned it had wired an amp cable from the head unit to the battery, and removed it at a later date, i believe she drilled a hole for the cable to go through, i was then told about the heating sometimes not working and when she took it through the car wash it leaked water where the hole was drilled when i picked it up it was working fine on all fan settings and it was very warm, then the next day it stopped working i took it to be hand washed and when it was done the heating worked fine but the next day it did not work does this sound like a grounding problem? and where do i start to look.
Please help its freezing
John
