Bought a used lentech to put in my 89lx....Put it in everything worked fine ... Went to drive it today and it keeps staying in od you cant shut it off with the switch checked power to everything and thats all good BUT you cant hear solinoid kicking on now?? I was wondering if anyone else has ever had that happen like it just went south?? Is it just a quick fix or what would all be involved in changing the solinoid out?
