Mondeo Mk1 1.8 LX 1995 Oil Pressure Light

very rarely the bulb. find the switch, pull the lead and earth it, if the light works you know it is the switch, otherwise it is wiring or bulb.

Thanks, hopefully will get around to checking it out today. I have heard it's a bit of a pig to get to.

Now oddly enough, the light on my 2.0 Mondeo failed after an oil change. They tried the trick of shorting the lead to earth, and then nothing.

Now the temperature is dropping again, the switch is working.

I think it's a little bit loose in the dash, and when it cools, it makes contact.

more likely the contacts in the switch are smothered in oil because the switch has started to leak.

No, the switch was fine, the garage inspected it in front of me.

It's definitely linked to the weather, and something upstream of the switch.

Tested it yesterday and earthed the lead and the light came on. Going to get it changed this w/e

Thanks for the TIPS.

Changed switch, ok now.
