[Vwdiesel] wiper relay

[Doug]

My Caddy has been sitting most of the Summer. Friday, I was driving it 
and it started raining. When I turned on the wipers on intermittent, 
nothing happened. When I tried continuous on hi and low nothing happened 
initially. Then, the wipers moved and stopped in the middle of the 
windshield. I kept changing positions and eventually got the wipers to 
go to home. What is going on with my wipers? Is this something that a 
new wiper relay will correct? It is an 81 Caddy with the intermittent 
wiper modification.
