Hi I am trying to find out where the fault lies in my car. I have an Audi A4 2.4 V6 B5 1998 with climate control.
A few weeks ago when motorway driving the temperature gauge dropped to about 70 degrees C - I ignored it assuming the cold weather was the reason.
Then a couple of days ago the temperature gauge stopped moving altogether and now stays on minimum.
I think my engine is running a little rough and sometimes when I switch the engine on when it is still warm it has a little trouble starting - not a nice clean start like normal. It starts perfectly every time when cold.
Then the blowers packed in but came back a day later - i think this may be a separate fault. The blower motor may be on it's way out.
When the blowers started working again i immediately turned the heat up to full blast and the air that came out was very hot just like normal.
I have been told that my thermostat is stuck open, but why would i get lovely hot air coming through if the thermostat is at fault? When i done the test it was on a cold engine and i immediately started driving - within minutes the hot air was coming through.
So two possible faults but which is it?
Thanks in advance
