Hi. You'll have to excuse this but am new to this site. Is there anyone out there that can solve my problem, I have a 1999 'R' reg Astra 1.6. My alternator died and was replaced and a second hand battery fitted, then about a month later the 3 dashboard dials (temp, speedo & petrol) started playing up. The handbrake light and the petrol light would come on then the dials would freeze, they would dance up and down and then they would all go to zero regardless of whether or not I was driving or at a standstill. The mileometer would also go blank. I have taken it to three garages and all have come up with nothing. They have changed the speedo sensor and it is still the same. the problem is intermitent. Please please please can someone help me or point me in the right direction so I can go back to the garage. Thanks.
