Cool A/C airflow ‘93 XJ40 3.2lt

I have restricted airflow through all the vents - despite the fan speed under the right (driver’s) side dash.

I seem to have vacuum, and power to each of the gates.

Is there a pollen filter I can service? Where? How?

What can I check, service, replace to correct the airflow of the air conditioning?

Thanks. Paul

It sounds like only one of your blowers are running?

Both need to operate to get sufficient air flow because if only one is in operation it will blow the majority of the air into the other blower housing and not out of the vents.

If this is the case, check that you have power on the brown w/blue tracer wire to the blower. It should show 12v even with ignition off.
