Gday guys!
Really hoping you can help me with this problem Iv had with my tempriture gauge for the last 18 months.
It has two issues.
1. Sometimes it'll be sitting in the normal range then jump strait up to hot. It also occasionally does this when I first start it in the morning when the car hasn't even warmed up. To fix it I usually bang on the top of the dash and most of the time it comes back down. I pulled the cluster out the other day and waited for the gauge to play up. When it did I jiggled the multi pin connector and it went strait back down. I had a bit of a play with it but it doesn't seem to be loose or anything like that. What do you think I should do?
2. When the car has heated up to normal, if I turn the headlights on, the gauge goes up a little. High beams, goes up a little more, a/c plus high beams and its in the red. Turn them all off and it goes strait back down to normal. So I'm thinking it's an earth issue but I don't know where to start. Where is the earth connection for the dash?
I did take it to an auto elec here in Alice Springs but after having it booked in for a week, the day I took it to him he had "forgotten" to write the booking down and said he could spend a quick half an hour on it. After that he tried to tell me I need to replace the radiator to fix the issues. Now I am pretty sure that the radiator has nothing to do with the issues. Extremely frustrated as I live four hours out of Alice and took a day off work to get it to him!
Hope you guys can help me!
