A couple of times this week it seemed when I slowed down or turned the Blower was stopping. FYI I usually rum the HVAC in Auto mode... Tried a couple of times out of Auto Mode to see if I could make it do the same, but couldn't.

Today while coming into work again in Auto Mode and the Engine Temp coming up, no fan at all. Take it out Auto and change the Fan Speed, no Blower....

After a few minutes I decide to hit the passenger side of the Center Counsel and bam starts to work...

Is there a relay in there?

The blower is located behind the glovebox, no relays for the blower are in the center console, just wires that could have come loose. Does the 2002 have yellow blinking lights that activate when turning on the engine, like the earlier cars when an error is detected?

It is possible that the cabin temp sensor is dirty and that the fist bump dislodged dirt and allowed it to work again. Or just the plug is loose, or, the blower switch is acting up.
