P38A Retrofit heated front screen

LR-hobbs · 2025-05-04T21:04:44+0100

Hello all
I'm looking into upgrades for my new P38, and was wondering if it's possible to fit the heated front screen to a non heated like we did in our old discovery 2.

I've checked the fuse box in the engine bay and both relays are missing, however there are wires going into the slots in the bottom of the fuse box.

Is this as simple as fit the relays , fit the switches , plug the screen in and get it programmed.

Or is this a pipe dream.

Cheers

I thought so p38s had a heated screen!! Is there a space for the relays in the fusebox? What year is it? Do you have the button on the hvac?

Yes there are two spaces to fit the relays in the fuse box
It's a 1999 4.0
And no button on the HVAC

Ok so you'll need a new hvac unit as a minimum.. unless you diy it

That should be easy enough, do you know where the wiring would be for the screen? Same place as the discovery 2?

Does it have the option on the hevac? It should have a heated I think

If so the plugs are hidden under the metal plates at the borrom corners of the windscreen just above the pollen filters.

The wiring may not be present at the HEVAC.

Is it a separate multi plug ?
