Vanagon dash removal is a lot easier than a lot of other vehicles. If you are getting hot air from the heater with the lever off check the heater valve for proper operation. It is common for the valve to be bad or the cable liked-mis adjusted. Dennis

In the summer I put cold drinks in my original-style cupholders mounted on both sides of my automatic shift console. The heater leaks enough heated air in the summer to warm up my ice cold drinks in minutes. Not to mention, leaking heat into my already-hot interior. (I don't have A/C). I want to fix my flaps with new seals so at least this won't happen, but the rest is fine. I've never had a Vanagon dash out (yet), so I don't look forward to the job....
