My heater fan works on all positions and sounds like its blowing but no matter what position i put the controls on it doesnt actually blow any air. Well a very very little bit through the dash pad for the defroster. Its warm but doesnt blow but the fan turns on.....whats wrong?
Unless you have it set to blow through the defroster vents, you have a vac leak in the HVAC vac line. I'd find and fix it and then see what else is going on.
There's one feed line and it always cracks or leaks and it leads to only having the defrost vents functional (they're the default when there's no vacuum signal).
Do you have a fox III or SN95? Both have the issue but the source is usually a different location (SN's are in the engine bay and foxes are inside).
Look on the firewall. By the passenger hood hinge. There is a check valve mounted there. This is part of the main source of vacuum for the A/C system. Like HISSIN stated, if this is broken or damged, you end up with Defrost only.
Yeah looks like it isnt there anymore after my engine swap what the crap! Does anyone have a picture so i know what part it is and install it quick before i freeze my a** off anymore?
The vacuum reservoir is the black ball inside the passenger fender. It stores vacuum to operate the vacuum operated assemblies like the HVAC vent controls.
