Yes, the problem seems to indicate a faulty relay and the replacement is simple which you can do it. Pull it out and plug in the new unit and it is done.
However you should test if it is the cause first as the fan switch or it circuit if shorted to ground would cause the same problem.
Turn ignition switch ON and pull out the relay, if the fans stops, replace with another and if fan does not operate, the relay is faulty. The power window relay is similar so you can try by borrowing from it to test.
The diagrams I have is for a 2.2 liter and hope it is the correct one.
