Recently I had to replace the heater control valve when I installed the supercharger cause the part basically broke like they normally do at 20 years old. After replacing I didn't even test the heat cause my mind was focused on other things of course
Now that the cold weather is back the heater will not work unless I manually move the cable all the way towards driver side. Air will go back to cold and back to hot with vehicle running. After I re start the vehicle no more heat?
Also there is a water gurgling noise behind dash when I drive. Tried bleeding the coolant system but to no avail.
