Questionblower motor relay keeps going bad. works for awhile then wont shut off. ran toggle switch under dash but wire melted. have replaced blower motor relay 3 times. keep having same problem.
AnswerHello,
I have seen the wire run with a switch, but never saw the wire melted. You cannot run straight battery power! The wire must be fussed. Did you use #12 of #10 wiring? Anything smaller than 12 will melt. Was the stich rated high enough?
You are dealing with an old Cadillac. Because of their known problem with the resistor module for 20 years along with all sorts of common Cadillac problems, we are left as consumers out in the cold. (pun)
I know Cadillacs very well and the reality is they are great to drive, but they can be a money pit. I recently traded my Allante in for a less problematic suburban. The Allante was starting to show some of the ugly factory installed problems.
I understand your frustration, but it is time to wire properly with a fuse and sell it to someone else. The next thing that will go is probably the engine (Cadillac was notorious new for overheating and junk engines). 4.1, 4.5, 4.9 and northstar were junk! If you have gotten a lot of miles from your 1992, be grateful. To fix this correctly, it will cost you over $500 for a new module that is doomed for failure out of the box.
I am not trying to degrade your car and I am just telling you the reality of old Cadillacs.
Good lluck1
