A member here posted a heater article that may help you understand the operation: The Operation and Maintenance of the Heater for a Non Air-conditioned 1962-1965 Mopar B-Body. by Kevin Merkley http://www.1962to1965mopar.ornocar.org/ml-62-65heaters.html Careful with the rubber vacuum lines! See the 62-65 "Technical Tips and Links" page for specific suggestions on how to handle the lines etc. I don't think you need to remove the dash to get what you need accomplished. But getting the job done may test any mobility and arthritis issues! :) Sometimes I remove the seat to get better access to the under-dash Klingon technology. Gary H. -----Original Message----- >I will soon get my car back from the paint shop and wanted to tackle the heater problem. The vents controls that switch from A/C to heat to defrost work fine, and the vacuum line in is OK. However, the vacuum to open the valve to let hot water in is not working. The valve looks new, so I assume the problem is in the dash controls where vacuum is routed to it. If I take the dash off I guess I can access the controls, but it appears I have to drop the steering column a bit to get the whole dash panel off. If the control is broken somehow (I'm not sure how it works) does anyone know a place to get a replacement for that?
