I have recently purchased a 405, 10 years old, 90000 miles. It has developed the following - Airbag warning light is on. From research on this website this seems to be due to orange cables under the seat not being connected properly. In addition this has developed to the temperature guage showing no reading, this developed into the temp. guage warning light coming on and a STOP warning light coming on simultaneously. In addition the engine fan seems to be permanently running. Are these inter related? Can some kind soul help me out. Cheers Matt
