I have had a bad smell in the car for a while, I have had all the flex hoses of from the heater and under the wings of and I found a mouse had been there, but nothing too bad. I cleaned these out, including the foam lining which was perishing and was smelly etc.
I though that would have solved it, though it didn't.
I noticed today that the heater fan would not work, while testing for a 12v at the switch (no volts) I noticed that the smell was coming firm the heater.
I then checked the fuse and it was blown, replaced it and blew immediately.
I guess the bad smell was the heater motor burning out?
What else could it be? and what is the fuse blowing?
Many thanks
