Hi everyone,
First post and im not much of an expert at cars but here goes!
Ive searched the forum and seen a few posts but nothing that really answers my problem.
Here goes,
For the last day or two the heater/blower in my 56 plade Grande punto will only work on setting 4, full blast!

Does anyone have any ideas? Im not sure if i could fix it myself, does it sound like an expensive job if it went to a garage?

Thanks for any help in advance!!
