cruise control light blinking t100

I have a 1998 t100 sr5 xtra cab. just bought the truck so i dont know if the cruise has had a problem before. at any speed i turn on the crusie and all i get is a blinking light on the dash. cruise does not engage. nothing looks unlpugged under the hood and all the fuses and relays check out. speedometer seems to be working correctly, I see no other problems with the truck and have reset the computer by un hooking the battery for a few minutes. hope to use the cruise on vacation soon, without going to the dealer. any ideas.... thanks Bill

the cruise probably has a code stored, and I am almost pos. u will have to take it to dealer to have them check it, and find problem on that part vehicle.

Is there a way to clear the code to see if it comes back. the truck was a total and i have rebuilt it. the code may be a result of the accident. i can clear the ecm codes but unsure of these codes. also is the a service manual that would be helpfull for this kind of truck what does the standard service manual cover would it cover this type of problem. thanks bill

let me do some checking on that tomorrow and I will get back
