Jcb tm310/320 air con blower fix

[davidroberts30]

This works for all 310 and 320 up to 2017

1 of the only bad things I can say about these machines is the acces to the heater/AC matrix...
Seat out, degas ac ,side dash out
Near 2 days work....

Anyway,panel off

Filter out

Start small and low to the left

Hmm yes defo needed doing

Once your in and can see where the matrix is make the hole a bit larger so you can get a hand in

Debur the edges as they obviously slice your wrist or fingers open.

25mm of water trapped in there

2 drain holes marked

Scratch or brush then airline the matrix clean

Had some rivet nuts

Bit of instant gasket

Bit of old plate

Why o why couldn't some student designer in jcb come up with a stooped idea like I did
1.5 hour it took me

If the full blow isn't restored,especially on earlier 310s check the duct pipe by the fuses hasn't come off

or the trunking under the cab hasn't dislodged,check and use mastic if necessary

Worst thing on these is no recirculation filter so if you drive with door open(I bet you don't leave the fridge or freezer in the house open and wonder why it doesn't work)
Dust in the cab gets drawn behind the panel behind the seat

so some black duct tape to seal it up


I didn't think this 1 needed doing as the airflow was acceptable but there is some difference now
