Ok here's what I have.
A 1989 560SEL with barely any heat.
Heat barely works with fan set to low, heat on max, and econ setting selected.
If non-econ (a/c unit on) setting is selected then no heat at all. NO heat on any other settings than above. What the heck is wrong??
Thanks!!
p.s. thank God for heated seats!!!!!

The monovalve is located under the hood in the firewall bulkhead, just left of the battery.(sitting in the drivers seat facing forward)
Do you have heat at idle or at slow speeds, and as you accelerate do you have less or no heat?
If so monovalve....
Let me know
