I recently got this '74 Rx-4, and it's got a few bugs. The horn rarely works, the seatbelts' locks don't work, so you can't even pull them out. Anybody know what I'm talking about?

 

try hook up the wires to a diffrent horn it may be just the orn that is defective and not the wiring..

 

and about seatbelt, take them apart and put them back together thats what I did with mines...and finito no more problems

 

2 piece or 3 piece seatbelt. For 2 piece, these are electrically controlled so if the wires are disconnected, it wont work. In addition, unbalanced installation can cause similar problem.

 

Hello GTX79

Another RX-4 in the works, Kool!!!! What year?

Unfortunately, I don't have pics, yet, but I did find out the horn's problem. Turns out the fuse to it was falling apart. As for the seatbelts, I need to know where the power comes from. Is it a fusible link, or is it just a sensor problem? They sort of work when they want to now...

 

PM me your e-mail addy and i will send you the diagram. Its from a RX-3 but wirings are all the same.

 

I think I found out my seatbelt problem. Turns out it's the acceleration sensor that's shot. I can't get a new one, so is there anyone in Calgary who has parts like this? Don't know who money orders anymore, and online order is out of the question. The horn also still has issues. Aparrently, it only works when the ignition is locked, and the key is out.
