4WD Light flashes 9 times...
After about 10-20 miles of highway driving, the 4WD light begins to flash. 9 flashes, five second pause, 9 flashes and so on. Any ideas?

Hi Navyguns:
Welcome to our FTE forum
This problem is most likely related to the clunking during turns. Unplug the AWD module under the driver's seat to see if it goes away.
Code 9 means there is something wrong with either the sensors (2 on the transfer case) or the Transfer Case Clutch.

AWD Light Flash 9 Times
I am experiencing this problem also and my cruise does not work. I have 97 and from what I have found is the 97 is the odd one out of all the Aerostars. The cruise is the electronic type (Not the Vacuum Servo like previous years) and also I have the 5R55E Trans. Where are these sensor located on the transfer case? There looks to be 3 sensors. I have the cruise control issue down to either a speed sensor or a pinched/broken wire. I am leaning towards the speed sensor but which one on the transfer case would I replace/check. Any info would help.

would a very much so bad almost blown up cv axle cause this? the new one we bought will act like it's binding up when we turn the wheels right and try to go. then will make a loud clunk then flash the 4wd light.

The final solution...
It's been a while, but here is what I ended up doing. After running the vehicle with the AWD module under the driver's seat unplugged, and no 4WD light flashing, I took the vehicle to my local shop and had him check out the transfer case. Turns out, the transfer case was going bad. The wear inside was causing one of the sensors to be hit by a turning component and damaging the sensor, which led to the warning light and the clunking in turns. You could see on the sensor where it was being struck.
His estimated repair cost for a rebuit transfer case? $1300.00
An Ebay search turned up a new one, in the original Ford box and wrapping, for $375.00 (including shipping). Called my Ford Certified mechanic nephew, Jed, and he installed it for $285.
That was last fall, and its been running like a champ ever since.

glad you got it fixed and back on the road
had the transfer case/driveline recall been down?
is the rear driveline steel or aluminum?
aluminum is the recall TSB required replacement
dcrb,
which part is new, cv half shaft or transfer case?
probably a failed rpm sensor on the transfer case or the wiring, common failure on aero.
1 located about front and rear drivelines output.
search forum for additional info.
been covered bucu times
fordnu1,
the rpm sensor that is probably causing your problem is the one on top of the rear differential
if not, then get a Ford Serv cd of DVD for 97 off internet or ebay.

the only reenginnered parts change was the driveline from steel to aluminum.
they could not get the torsional bending resonances down low enough with the steel dl which cased damage to the TC case and internals.
they replaced the rear case section and output shaft at the same time because of the high percentage of damaged returned cases they were seeing.
this was a required Federal Safety Board recall, not something initiated by Ford.

Alot of replies but none answered the question about the cruise control. I am down to only a few things. One thing I am wondering about is the speed sensor. Where is this located for the cruise control. Knowing Ford, this sensor also is used for other devices. I have no problem with anything else not working. I plan to clean and inspect the 3 sensors in the transfer case and most likely this will take care of the blinking awd light. Any help with the cruise would help. Thanks.

repeat of reply above
there are 2 rpm sensors on the TC, not 3.
fordnu1,
the rpm sensor that is probably causing your problem is the one on top of the rear differential, may also be tone ring, wiring or connector problem
if not, then get a Ford Serv cd of DVD for 97 off internet or ebay.

this tread is started by another member for their problem and is getting confused and too long with tag alongs
please start another thread with your specific questions and symtoms
