'94 C280 AC and Heater blower help
 

Hi all,

The fan that blows air into the cabin seems to have crapped out. The climate controls work fine, that is, all the lights come on when pressed in normal operation but no air. My friend said it's a fusible/fuseable link somewhere that might have blown and some on the internet say it's the blower regulator. How do I figure this one out? How do I go into diag mode on the climate control... Thanks in advance....

addition: aux fan
 

Oh, forgot to mention the aux fan crapped out at the same time making my car overheat... FYI: rad has hole which will be replaced this weekend... thanks...
