Hi I have a 1995 holden VS wagon the aircon only works at full speed but I know what that is and how to fix but the problem is even when ac is on full the vents in the middle at the front work fine nice and cold but the vents at the back of the center console passenger and drivers side have very little air coming out from them if any at all and I can't figure out what the problem could be. I'm just wondering if there's any ac filters that may need to be replaced or if it's the heater/ac blower motor if it has one please help with any suggestions.
I can't find any info for the vs aircon system. Any help would be great thank you in advance

Often nit is poor fitting or deteriorated seals on the air duct tunes, you can loose a lot of air flow from these and often the result is little air flow at the rear vents.

Only 1 vent in the front of dash above the stereo works fine the front passenger and drivers side have basicly no airflow at all same gos for the vents at the back of the console that's why I'm stumped

No filters on this model, you may have to remove the outer dash vent tubes that connect the outer vents to the blower case, also check that there is no build up of leaf litter in the blower motor, over the years this can build up and block air ducts, I have even cleared mice nests blocking air ducts, you need to get in and check these.
