Hello there. Have u got climate control? Put it on auto and see if your fans come on. They should be on when in this mode. Is your temperature gauge doing weird things when driving and warming up in the mornings? Try changing the coolant temp sensor,that might help and check battery connections,make sure they are nice and tight. Try A & R Auto Services Ltd. Telephone No. Nottingham (0115) 929 6602. I found them very helpful and definiteley know what their doing. Hope u get it fixed.
