Jaguar xk8 1998 is there air filter associated with the air conditioner..Hepa filter??

It is located under the panel in front of windscreen

it usually put in on the low pressure side of any air conditioning system, it will be on the largest size alumunin line that comes from the compressor, some have a blue cap covering the service port.

Chances are it is a clogged hepa filter. There located inside the glove box. Take all the stuff out of the glove box, there is a little hatch at the back of the glove box, remove it and pull out both filters. If these are ok there is a service builten, See your GM dealer, parts are not that much and you can do it yourself. Have them run your vin. Getting back to the cabin/hepa filters, there about $75.00 at the dealer, maybe there is aftermarket available where you live Good luck Kirk fe6fc

??????? hepa filter ? if you are refering to a cabin filter you dont have one 2001 and up have them

under the passenger side dash ,have done one not long ago but i wouldnt remember ,like a machine i just do it hard to describe i just look and do it ,

The cabin air filter is located behind the glove box, you will have to remove the glove box, behind the glove box is a cover about 1" high and 7" long, remove that cover and you will see a tray that holds the cabin air filter, remove the tray and you can replace the paper cabin air filter, I recomend using a Toyota cabin air filter, the Toyota cabin air filter is a HEPA air filter and is available at any Toyota dealer for about $ 30

check and replace in cabin air filter

unsrew the jaguar cover take off the oil cap then usrew the front cover and replace the air filter

Cut the plastic cross brace in the glove box opening with diagonal cutters in the area shown, and discard it.
Remove the bolts, the screws and the glove box frame.

1. Remove the filter lid (A) from the evaporator, then pull out the dust and pollen filter (B).
2. Install the filter in the reverse order of removal. Make sure that there is no air leaking out of the evaporator.
