Question about 1998 Toyota Celica
First thing i would do is to check for a feed to the motor ?? then if need be run a power feed to it to close the roof .then work backwards to locate the lack of feed .could be an earth issue as well but you will need to check it out with a meter to see if earth is ok or just run another earth as a good measure then when you know earth is ok put a power cable from the battery to the motor to make sure its working ,then as stated work backwards looking for the feed so the next thing is to check for a feed from the switch which should run to a relay then on the relay you will have a permanant 12v feed to the relay and the 12v feed from the switch if you have this and the relay isnt clicking check the earth on the opposite side to the switchable feed ,the other side of the permanant 12v feed will run to the motor ,simple but be carefull because the relay will reverse the current flow to lower the hood so you will have one feed but the relay will throw another contact to reverse the feed but if you play with this with the test light you should be able to work out the wiring ,then when you have worked out the wiring you should be able to locate the fault .Now some types i have worked on use a sort of circuit on the motor to reverse it like a wiper motor self pàrk mechanism ,wher eit will go one way then when it reaches the end it will lift the contact and go the other way ,with two set of contacts one the feed and another for the earth .if you disconnet the wiring plug to the motor and use a twin flex cable from the battery + and - to the motor then if it will not close just reverse the cables and it will go the other way and close
