Fuse first. If it works at the highest position and no other, then it's the inline resistor. Remove and replace.

Doesnt work at all mate

Any idea on location of fuse its right hand drive

The fuse should be located in the passenger side kick panel.

Hang on and I'll find you a diagram.

Fuse #25

try tapping on blower motor while sw. is on and ignition is on. may just be bad spot in blower brushes. it`s the easiest to try first.

All sorted cheers

The 3 wire plug on the motor has got a bad connection seems to be ok now

Fun.

Yes. The 4.0 is a noisy motor. Tough as nails...but noisy. A bit of piston slap and lifter tick is very common, some had it from the factory. Neither affects engine longevity.
At 230K, mine sounds like a Cummins when it's cold, and Singer sewing machine when it's warm, lol. You'll find that's more the norm than the exception.

If you have a Fram filter on there, switch to Mopar, Wix, Purolator, Napa, etc. The Fram drainback valve doesn't mix well with the cockeyed filter mount on the XJ leading to dry starts. That might be your startup lifter tick right there.

Thanks for the top advice guys

Yep just a little noisy no knocking as such

P.s what is a fram filter?
