I have a 2004 that will not put out any heat, the factory deck is no longer working and have installed an after market one. Any suggestions

Press the "Scan +" and Power button at the same time to show "A/C Temp" on the display. This shows the current position of the baffle, from 0-16. If the display always shows 0, it could be the baffle. I just had to replace mine, $400. Good luck.
