The truck has 12K miles on it and I've never had any problems with it.
The Climate Control Module was cutting ON and OFF on my way to work this morning....It was also blowing hot when it was ON.
When I went to lunch 5 hours later... it was just blowing hot, but not cutting out.
Then 3 hours later when I went home, it was working fine.

I think it is some sort of electrical problem.
Has anyone heard of anything like this before?
What do you think it could be?

Thanks for the help.
