I have a 1999 1.6 8v single point injection astra, the engine emissions warning light has come on and also the engine cooling system warning light. When the dash warning lights come on the rad fan and A/C fan come on and it loses a lot of power and becomes erratic when idling. 90% of the time the lights are on, the engine does not get up to temperature and the guage never seems to move from very cold however the heaters blow warm so i am assuming its a problem with the sensor not reading correctly.
I have autodata and have the tests to carry out listed. However i cannot find the fuse box to firstly check the fuses to make sure they are all good.
Can someone tell me where the fusebox is please and does anyone have any suggestions as what to go about doing first? I am going to replace the CLT sensor and clean the idle control valve and throttle body. Any other suggestions are welcome. The car has its MOT in a month so i need to sort this out before then or they will fail it.
