Where I would start is at the switch. Pull it out and disconnect the wires. See if you trip a fuse when you connect the two wires yourself. That would at least eliminate the switch itself from the problem.
After that, you'll have to check the wires to see if one of them is grounding when it shouldn't. You can do that with a multimeter and see which of the two wires show a ground using the ohm setting.
www.jagrepair.com will have the wire diagrams you will need to go deeper, but we are here to help.
So, according to the wiring diagram, at the fuse, the BROWN wire is coming from the battery. This wire is spliced into Fuse Locations 4 (Radio Memory) and 11 (Trunk Lighting) as well.
1. First thing you could do is pull the 10A fuses at 4 and 11 and see if that helps. If the flashers work with fuses 4 & 11 pulled, then come back and let us know. If they don't, keep going.
2. The BROWN/ORANGE wire going into your switch carries the battery power. First, do an ohm test on the BLACK wire to ground to make sure the switch is grounded. If you cross the BROWN/ORANGE wire with the LIGHT GREEN/PINK wire should fire off the flasher. If that pops the fuse, then the switch is safe.
3. Assuming that works, the next thing to suspect is the Flasher. That is somewhere under the dash panel. I don't know what it looks like, but it should have 4 wires going to it. (1) Light Green/Blue, (2) Light Green/Pink (3) Red(?) and (4) Black. I would run an ohm test on the BLACK wire to ground. Make sure that the flasher is grounded. The RED wire should not be connected to anything, so it might not even exist.

Hi, thanks for the latest info

Removing fuses 4 and 11 the hazard switch still blows the fuse and no indicators
Grounds are connected on both relay and hazard switch, beeped tested
With ignition on we connected brown orange and green pink using a wire nothing happened fuse didn't blow nor did the flasher pop off
Therefore is the switch at fault ?
I did put a 25 amp fuse briefly in to see if the relay clicked it did, but no flashing of hazard button or indicators working at any time
I can’t say for sure whether the switch is at fault until we can get the lights to come on without it.
I don’t have the electrical diagram in front of me, but I thought by crossing the brown/orange and the light green/pink, that should have sent power through the flasher and to the lights. I need to take a second look at that.
I want you to be able to activate the light, bypassing the problem. The other way we can do this is by going in reverse direction. I’ll make recommendations later today.

Thanks, if I press the button in very slowly I get about 2 clicks on the relay before the fuse blows
There are no dashboard indicator lights or indicators at any poiint
`Question - does the indicators need a working hazard switch to work ?
I'm assuming that the turn signals work when you use the stalk on the steering column. If they work, then the only suspect parts can be limited to: (1) Switch (2) Flasher (3) Lighting and Turn Signal Switch. If they don't, then I have underestimated the problem.
The Flasher should operate the lights if it sees power on the LIGHT GREEN/PINK wire. What happens if you disconnect that LIGHT GREEN/PINK wire and apply 12v power to LIGHT GREEN/BLUE wire at the Flasher? That should bypass the flasher, and we should light up the turn signals. (You can cross it with the BROWN/ORANGE or GREEN (with ignition on) wire to do this, if possible)
Oh, so the indicators don't work, regardless whether you use the stalk to indicate a turn? OK. Have you checked all the light bulbs. It could be as simple as that. I would start there. After that, I believe if the fuse burns out when the switch is depressed, there's likely a problem with the switch. There is a handoff between battery power and switched power at the LIGHT GREEN/PINK wire.
Does the switch blow a fuse when you press it with the ignition off, no key in the steering column? The switch should work with the key in or out, so I'd like to know if anything happens with the key out and the switch pressed.
When you pressed the switch button slowly, and got the clicks on the relay, did the switch ever illuminate, or you don't know.
1. Brown/Orange (key off, disconnected from Hazard Switch) & Green/Red (disconnected from Hazard Switch) - I'm hoping your left rear and front turn signal lights turn on.
2. Brown/Orange (key off, disconnected from Hazard Switch) & Green/White (disconnected from Hazard Switch) - I'm hoping your right rear and front turn signal lights turn on.
3. Disconnect the Green wire at the Hazard Switch and press hazard light switch with key out -
4. Disconnect the Brown/Orange wire at the Hazard Switch (green should be connected) and press hazard switch with ignition on -

According to the Jaguar parts website, there were 3 versions, DAC 10104, DAC10201 and DAC 11170, which changed between 1991 & 1996. I don't know whey they changed or what is the difference between them
In theory, your car has DAC 11170 as a 95 car. I also have a late convertible which should have the same switch. I'll look at my car at the weekend.
If your switch looks exactly the same as the one in the advert, including the wiring plug, I suspect it would fit fine.
Hazard switch blows fuse
