I own 1998 ford ranger 4x4 Super Cab, 4.0 liter V6, 124000.
Recently the dash air vents stopped working when the heat or A/C is on. The fan seems to be working properly, but only blows air through the defrost vent. Fan spd switch works, I get hot air when heat is on, get cold air when AC is on, but only through the defroster vent.
Could I have a vacuum problem?
Recently had the intake manifold gasket replaced, Could something regarding vacuum not have been put back properly when that repair was done?
Any suggestion would be apprciated very much

Thanks for the insight. I did my best to check all the lines, I did not find any leaks. I noticed there are many things under the hood that the lines connecct to. Example: heat valve. Question is: what creates the vacuum, I want to check if the vacuum source is malfunctioning.
