Well I definitely have the symptoms of a defective heater booster with the air blowing full power after approx 10-20 secs stone cold on start up.... but I’m just wanting to find out if the booster is behind the dash on the early w211 ? Mine is the 2003 model.....
 
The fan and functions work fine it’s just on 1st start up when the air blows out on full after a few secs there’s no hot air where the booster come s on, just cold air now.... so sounds like the dash is coming out lol and I’ve watched a YouTube clip on how to and doesn’t look too bad just have to be careful with the air bag plugs....
