Didn't you just prove my point - that you can work and fix modern
The original post refereed to " I can't work on modern cars". In
your post, you
just proved that you can indeed work on them - no matter how complex
the system is (in this case HVAC). I made no references to cost.
I had a similar problem on my Audi, took me 2 days to trace the
to a bad ground (familiar problem in British cars) - tools needed
a good workshop manual and a digital volt/ohm meter.
I still don't buy the argument that modern cars are not for the
hobbyist. A good manual, a good set of tools (albeit different -
like fuel pressure
meter, diagnostic readout, volt/ohm meter etc), an understanding of
system works and a methodical approach to diagnosis will help you
95% of the problems on modern cars. This approach is used in fixing
car, modern or classic.
