Hello all, well I've got a long term problem. first the coolant light came on with the A/C fan running every 15 secs. Replaced the coolant module, but it was faulty, it stopped the fan, kept the light and would not start the cooling fan when hot. Have now tried another module, and it's the same as the original module, light, A/C fan every 15 sec and no cooling when very hot. This tells me that the problem is not with the cooling module, if the cooling fan was defective, could it cause these problems? By the way the A/C has not worked for 10 years, without any problems. Anyone any ideas where to check next. Have replaced temp sensor, ( the one that shows water temp on the dash).
