windshield wiper initial delay

I have a 1998 honda accord LX and my windshield wipers don't start immediately when I turn them on. They used to start right when I turned the switch on in the morning. Now there is an initial 15 second delay
before they start moving. At first I thought they had frozen to the windshield, but I lifted them up and they weren't stuck and still didn't move. Then a several seconds later they started to move. I've tried all positions... delay, slow, fast... but regardless of position there is no movement at first, then after the initial delay they work fine. After I drive along for a few minutes if I turn the wipers on again there is a brief delay of about 2-4 seconds before they start. I tried them when I got in the car this afternoon at lunch time, and the delay was short... 2 seconds... unlike the longer delay first thing in the morning. Could it have anything to do with the cold (gets down to the high 30s at night around here in northern california)? Is the motor or a relay going bad? Once the wipers start working they work fine. They always responded immediately whenever I turned the switch on up until about a month ago. Any ideas what is causing the delay and how to fix it? I don't want them to totally fail on me sometime in a rainstorm. Any suggestions would be appreciated. thanks.

My wipers did almost the same thing a couple of months ago on my Civic SI 98. They did not start right away, short delay of 1 -2 sec, and were very slow on the first pass. After that they behave normallly. Of course I did nothing and, as luck would have it, during a cold and very rainy day here in Montreal a couple of weeks ago I get into my car after work (interior parking) and got out. It was raining like crazy, I turned the wiper on and NOTHING! They did not move at all. I had to go back to the parking the best I could because I could not see, left the car there and took a taxi home.
Turned out to be the motor itself that was fried. My advice... don't delay! fix it now!

the integrated control module (at least in our '93... I expect it's very similar in yours). But we can probably put the wiper motor on the unlikely suspect list; this behaves more like a switch contact that has hardened dielectric grease on it. The "continue" wiper in the motor doesn't affect the start-up (and that really isn't a common failure except in really old cars), so that leaves the control switch as the primary suspect.
