Rear light issues

[bkcooper]

New to the site and need some help...Sister In laws '99 Windstar has gone crazy...With nothing on Rear Running lights will come on for about 5 seconds and go off until battery goes dead....Will do this until you turn on headlights...Is fine then...BUT...Rear turn signals will not blink correctly....May blink 3 out of every five times....and at times Turn signal will just stay on ......just started this all of a sudden and they had to quit driving it...Thanks

bkcooper,

Did you ever find out what the problem was? I have exactly the same issue on my '99 windstar.
I think, it might be the REM.

No, I havent looked into it any farther..I went to the Ford dealership and that part (REM) is about $450...Unless you can take one out of a junk van...But all the forums I have looked at seem to suggest the REM...Let me know if you fix yours...Thought somebody would help us here...

Give the people here credit they are tech's who do have a life, They are not setting there waiting on someone to ask them question after question.

Hey Guy's

I had the same problem on my 99, turns out that it was a Generic Electronic Module (GEM) located on the passangers side in the back behind an access panel. I got one out of a salvage yard for $50 if you get one from the Dealership they want about $450 and a program fee of about $150.

bkcooper,

Thanks for the replay. Now I'm convinced its the REM. My rear AC blower started acting up as well. Today my wife couldn't even start the van. From her description it might have been the fuel pump (also controlled by the REM)
The only thing these problems have in common is the REM.
My local Ford dealer wants $400 plus tax for this part. Didn't say anything about programing. I found it on the internet for $300. Didn't want to spend the $300 without a second opinion.
The junk salvage idea from 70Z22 is even better. I'll call around tomorrow.
Thanks for the help.

Maybe even check ebay.....I have noticed that some salvage yards list parts on there.
