Need advice. Daughter's 2010 Edge puked coolant on the parking garage floor where she works and of course started steaming. I figured a bad hose or maybe radiator. Had the car towed to the house. I could see nothing obvious so I filled the reservoir with water a cranked the car to get it to operating temp and again to see if there was an obvious leak.

 

While bringing car up to temp, thought I would turn on A/C to expedite the process. A/C compressor kicks on fine but blower motor does not work. Tried it in A/C and heat mode...nothing. Also noticed that when car got up to temp, neither radiator fan ever came on. The car ran for a good 30 minutes at operating temp without ever overheating or leaking anywhere. Both top and bottom hoses were hot.

 

Could an issue with the A/C blower not working cause the over heating? Are the radiator fans and the A/C blower some how interconnected to work together? I'm really puzzled and not sure where to start.

 

Any thoughts at all?

 

Thanks

Pulled the blower motor under glove box. Had 12 v to motor tested on bench an ran good. Reassembled and blower is now working. However, neith radiator fan will come on. Even with the A/C on. Also compressor cycles. Engaged for 2 minutes and disengages for about 1.

 

Removed the radiator fan unit. Both work with 12V direct to each motor. Have about narrowed it down to the control module. Now shopping.

Stick with OEM for best results.  Dorman or TYC might also work, but watch for loose/reversed connections.  Also, don't throw away the old control module until you have the new setup working right, for a while.  Aftermarket modules can be ... unreliable ... sometimes.

2nd on using only Motorcraft. Others have been disappointed with the aftermarket units. To the point of pulling out them out and replacing with Motorcraft. Noise, vibration are two problems they reported.

Got the new fan assembly installed and everything appears be working as it should.

 

The only mystery, to me, is...since this is a "sealed", pressurized, system, when the car puked coolant on the ground, where did it come from??

One possibility you have the 3.5L engine, is water pump may be failing. Check your oil dipstick and see if any coolant has entered to oil. Oil with coolant in if looks milky, milkshake color. If so the water pump may be failing and needs to be fixed asap, have it towed. If not, have you lost any coolant? Is the reservoir low?

It could of vented out the coolant reserve also but I would have the oil tested to detect any coolant in the oil.  If there is coolant in the oil. stop driving it and get the water pump replaced asap
