Re: Multiple Problems for 99 & 03
You did check the respective fuses to start with? Did you check the fan itself if its working ok? Sometimes the fan is drawing too much current, fraying the new relay in no time. Did the fan work after changing the relay?
The temperature display problem is most probably the temperature sensor at the right side of the cooling radiator (you can see it through the cooling grill opening), or wiring.
