Hey Guys

Had a problem with the right turning signal on my 2000 Disco II - it was the yellow relay in the compartment under the steering wheel. Replaced both left and right with new ones and the next morning the car won't start. Battery is good and turning, no spark. Once I turn the key to the on position, the temperature gauge goes all the way up, then down and the red "overheat" light stays on. Both green "M" and "S" lights are blinking, red oil and battery lights are on. The code reader gives out "Error". Please help!!! Thank you in advance!!!

 

Unplug relays you replaced and repeat tests again. Perhaps relays wrong style.

 

Same result with the original ones

 

How much tugging and pulling did you do to the fuse block?
Any force applied may have dislodged the fuse block from plugging into a harness plug.

Not sure if the D2 is set up this way but..

I would push on the fuse block firmly to try to seat it.
This is just a guess of mine - not direct experience.

Also - bad grounds can cause such behaviour.

But, since you were in there under the dash with the fuse block - you need to retrace steps.

The error on the code reader may just mean your ECU is not getting power
and you are not getting any codes as the ECU computer may not have any power.

Check all fuses too.

You are in a pickle for sure.

 

Put the old relays back in and then what happens?

 

SaME thing with the old relays, The fuse block seems to be firm in place
