hi!! glad to be part of the forum!!
please help.96 taurus wiper & blower motor giving me trouble for a long time!

the wipers work perfectly but go on &off as they please.
the ac also blows cold on all speeds but goes on &off .
i was told it was a chip so i changed ccrm.both the a/c and the wipers started working after took out pcm and left it out for 20 minutes .the a/c blew &could not be shut off.
24 hours later they both would not work.
i let the pcm rest 20 minutes again & both worked again!
the wipers stopped again but the a/c is still working 24 hrs later

should i change the pcm( ecu)??
or check wires ,fuses,relays?which ones?
how? what do you think is wrong??
thank you so much

How about checking the ground wire connections? Seems like you have power, but possibly the grounds are corroded.

Do you have a digital dash or digital temperature control?

[dov]

thanx poppy,no digital.thanx for explaining how to check ground
today a/c would stop & go as we drove.must be ground or loose wires.would fautly pcm do this??

If you don't have electronic automatic temperature control, it is definitely NOT PCM. I'd have to check but I think that if you had EATC it still wouldn't be pcm.

It sounds like poor quality connections.

Inpoirtant grounds are usually mounted on the left and the right upper radiator support, also you may look for one near the wiper motor. Certainly battery connections and cables at both ends should be examined and cleaned if needed.

2 mechanics said it was a chip and were going to charge $250 or300$to fix!!as you see from my post both wiper &blower do the same.i changed ccrm from salvage and was goingto change pcm but cant find one with the same #
one mechanic said its " the wires".but i really cant give him the car all day.my son fixes everything on the car,
and it was easy to change parts.not so sure howto check wires etc.
THANK YOU SO MUCH FOR ALL YOUR HELP!!!!

Would I be correct that the heater blower also goes on and off by itself?

[dov]

yes!!the wipers dont go on that often butthe blowe goes on &off every few minutes

While this diagram may not be specifically for your car, it is representative of many.


IF the blower is all the way on high, does the problem still exhist?

You might check G200 which I think is usually at the lower lip of the dash on the driver's side.

thanx again!!! it is to cold so we dont leave it on high.i will try.now the a/c goes on &off every second with each
with each bump in the road

dont know if you got it fixed yet but sounds to me like alot of others say you got a bad or loose connection somewhere with ground wire.

thanx!! a/c started blowing but stopped for a few days.ill check everything
