you must give details...what year ,,,
most times its the blower motor or resistors that feed the motor...remove motor and check for proper feed and grounds,,,resistors burn't/ defective,,
could also be the switch if its always the same position ...

with a volt/ohm meter this is not difficult..

Mine did that. After going to the dealership, I was told my control panel was bad, my resistor was bad, etc (they wanted $600, I said no). It was none of that. My blower motor was bad. When it wouldn`t run, I would "tap it on the bottom" and it would start, after a while it gave up the ghost. I went to Nordstroms on Ebay and for $35, got a fan motor from an Impala salvage with low miles and a guarantee. It`s worked great ever since.
