97 E420 overheating issue
All
I have a 1997 E420 that needed it's condensor replaced. During the diagnostic process, my Mechanic (whome I trust) identified that the auxilary fans were not engaging. The fans themselves run because I connected a jumper box to the fan itself and they engaged. I understand that there is a module under the fuse box. I also understand that there is a relay somewhere near the drivers side fog lamp. When testing the connection by putting a test light, I could see a pulse (test light would flash for a second and go out every 10-15 seconds) of electricity go to the fan but no constant power. What should i Replace. Also, in 95+ degree temperature, are the aux fans needed only when the A/C runs or can the engine driven fan cope with the heat. I noticed that even with the A/C off, the temperature still creeps up. Shall I order a new fan clutch? Any advise would be gratefully appreciated.
