THANKS jpb53.
Problem solved. Replaced Fan Relay located under the air filter in engine compartment. Brought in the part (AR473SB) and receipt and NAPA replaced it for FREE b/c, as you said, it was still under warranty (bought bad one 9/08). Would not have guessed they'd do that w/ an electrical part! NAPA dude explanation -- got a 1 in a 1000 bad one. Suggested I could extend warranty if need be by NOT bringing in orig receipt if it happens again
Since I've done this twice now, FYI to all who may care, easier way is from the top. Take out entire air filter assbly -- pretty simple. Don't crack rubber vent tube as I did. Takes all of 10 minutes.
THANKS again! This forum and folks like jpd53 have saved me thousands of $$ over the years. Plus helped me teach my kids a little about car repair.
