Cabin filter & blower motor location

Being as you say a 1990 XJ6, I am going to "guess" it has a single windscreen wiper???????, if so, it is what is known as an XJ40, and Graham can move this to the XJ40 area, where answers to your query will be thick and fast.

I do not believe that your year model has cabin filters, maybe your market did get them, but I seriously doubt it. My 1996 X300 does not have them.
There are 2 (TWO) fans and motors, one each side of the inner sanctom of the climate control system. Easy to get at HAHAHAHA, and they do fail with good old fashioned "old age". It is quite common for one fan only to be running.
Lots of write ups in the XJ40 section on this, and the remove and replace procedure is also in there somewhere.

The XJ40 has a more square appearance and has a single wiper:
Following Grant's advice to check for the "factory build plate" is a more technical approach!
When you confirm which it is, I'll move the thread to the right section.

Righto.
Forget the cabin filters, coz I still reckon you no got them.
Air flow via the vents on the XJ40 was a hit and miss, and IF you have only one fan working that will be the prime cause. Turn on the system, set the fan speed on HIGH, reach under the dash on each side and "feel" the A/C unit housings. You should "feel" the fan "vibration" on each side as EVEN. If the "vibration" appears stronger on one side, then the other side fan is possibly not working.
I have NEVER had them out, only what I have read here in the archives, but it is apparently not a nice task.
Check the fuses, the XJ40 has a HUGE amount of fuses for all sorts of things, and maybe the RH and LH fan are on a seperate fuse, dunno????.
The system also has "stepper motors" that control the various flaps inside the thing, and if one or more of them is hissy, then airflow may be compromised.
The only hands on I have had was my daughters '87 3.6ltr waaay back, and one fan was slower than the other, but a strong "scientific" kick fixed it then and it still works fine today.
