'95 Jeep Gran Cherokee: Bad smell when fan is on.

[pawn]

Hi!

Like the title says: whenever we turn on the ventilation fan, a bad
odour fills the car. Smells like a barn.

I don't believe there's a driving compartment air filter. Is there
something I can do? Is this common?

Thanks.

I too have this problem with my 96 Grand Cherokee Ltd. If anyone has
any ideas or knows what the cause is, please let me know.
thanks

Condensation drain tube is most likely plugged, and you now have a mold
and mildew factory in operation.

There is a kit that gets sprayed into the external air intake for the
cabin that is supposed to at least kill the mold and mildew.
