The heat and AC both began to fail intermittently about a year ago. Sometimes
they would work and sometimes not. A local auto technician thinks it's some
sort of control valve that he thinks (but isn't sure) is located either under
the dash or under the hood. The dealership service advisor isn't sure which
valve controls both systems.
1. Do you think it's probably this control valve they are talking about?
2. If so, where is it located?
3. What should I expect to pay for parts and labor?
4. Is it something I could do myself? I've done a lot of mechanical work on the
car myself - just no electronics.
Thanks very much for any help.
