HVAC problem - intermittent power

Hey guys,
when I started my '04 SCREW this morning, the HVAC dash controls started flashing (lighting) and there was a clicking accompanying this (presumably a relay). When the relay clicks, the HVAC is powered and fans, a/c, seat heaters are on. When the relay clicks again, everything goes off. This occurs continuously.

Has anyone experienced this problem? I searched but found no topics close.
Thanks.

Well, it is encouraging that there's no one who seems to have this problem with their 2004 f150.

Any thoughts on where or why this problem would occur? I'm thinking of a failed relay, but it's just a guess.

I'll be checking things out today and will report what I find, if anything.

Ok, I fixed the problem... by rebooting the computer (disconnecting the negative cable from the battery. Very odd, but it's resolved for now.
