Hey guys, I'm Nick, new on this forum. Just recently picked up a 1998 Grand Prix Daytona 500 #1388, 133K, love the car, runs great, even better its that awesome blue color. I've been trying to track down an hvac issue, it seems to be stuck on defrost and lower foot. When I turn the blower motor on I can hear it blowing and changing speeds, so I don't think its the blower motor resistor. It won't blow out the forward vents, just barely out the defrost and lower foot vents. I have not tried the ac but have it on max heat and temp seems lukewarm. Checked vac lines by battery and is not corroded. So from what I've read, I'm thinking blend door actuator, and that's about as far as my troubleshooting has gone. Looking for input as far as where to go next. I'd be nice to have heat again. Thanks guys
