I travelled 4 an official assignment since last month. When I returned I tried startin d car but observed ma batri was down so I got a batri charger to start d car wit his. But I noticed dat d temperature guage in particular was not working as d temperature indicator on d dash board did not move at all. I checked d cooling fans and observed they were workin, pls cud any bodi tell me wat is wrong wit ma car cos evrytin was normal b4 I travelled.
