Cabin filters are common only for 2k years onwards and most probably there is none installed in your vehicle.
The most likely cause of clogging would be the evaporator fins. Try using compressed air to blow from the blower motor end. Removing the blower motor would give you more room.

Thanks for the help, I suspected that it wouldn't have one. Please let me know if its safe to clean out the evaporator by my self as I do have some mechanical and elctrical knowlaedge on cars.

It is ok as you are not going to discharge the A/C freon. If you are able to get a cleaner that can be sprayed onto the evaporator fins to dissolve the dirt, that would be good. Compressed air is a must if you want to do a good job.
Open all doors while doing the job for ventilation as dust would be flying around.
Another way is to spray cleaner onto the evaporator core where the fins are and allow to dissolve for a few minutes. Use a garden hose with a little pressure and low volume to flush the fins and wash away the cleaner as well. Ensure the evaporator discharge hose is not clogged and it would flood the cabin if it is.
Note : Do not use any cleaner that are too acidic as it can damage the evaporator core.
