[Healeys] Heater query

[Bob Spidell]

Ah, good point Kees. On a road trip coming out of Death Valley on a 
115degF day climbing the Panamint Mountains my BJ8's temp started 
climbing rapidly towards 212. I turned the heater on full blast--not 
fun, but better than boiling. Temp held steady at 212 until we crested 
the mountains and it started to come down and we were back to just 
miserable.

I suppose you could close it if you don't expect hot weather and, if you 
think of it, turn it on if the weather turns.
