First Timer with heating issues

[widget]

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

hey, welcome to the forum.

try doing a search/posting this question in the mk3 section, they might be able to help. my mk3 heater has been a bit dodgy lately, not sure if it's the same problem but mine doesn't work on setting 1 and sometimes doesn't work at all. i have got a new resistor pack for a few quid off ebay (new part though) as these can sometimes be a problem.

i got a feeling it is water related maybe a grounding issue

Is it the motors that stop blowing? Or is the problem more the temperature of the air coming out the vents
