Dear John:

I too have a gas heater in my 1985 van. Originally I had no response
from the button for the auxillary heater. I located the fuses on the
left of the steering column and replace a red one and presto I have
grumblings under the van and cold air shooting out from under the
driver's seat.  I cannot locate any fuses on the right of the column.
Behind the heater button there seems to be a connection. Is a fuse
located inside this? I don't seem to be able to separate it.
Any suggestions as to why I don't have heat. Also the light on the
button doesn't seem to light up.
Thanks for your time.
Susan
