Rear Window Defog Problem, 96' 140 Body-help!

is the only thread I found using "defrost", "defroster", "defog", and "defogger" with "140" and "rear". With luck, it might possibly start you somewhere productive. Hope it helps-

Steve? Any ideas?

thanks for the link, will start looking at the relays, unles any one has other info

You should find the defroster relay on the right rear sidewall of your trunk. My 95 S had a small fuse box with a door, but this relay is too far to the rear to easily access from the door, so I had to remove the panel on trunk wall. Best I remember the relay was pink (??) I had to use wet or dry sand paper to re-surface the contacts inside the relay. This brought my defroster back. I did find a post with picture on this board so do the search you'll find good help here. Luck to you, DanielW

thanks for the tip, will let you know how i get on
