To replace the driver side pushbutton seat belt buckle on a 1997 Toyota Previa, first, remove the plastic cover around the seat belt assembly by unscrewing any screws or clips. Disconnect the seat belt buckle from its mounting point by unbolting it and unplugging the electrical connector if equipped. Install the new buckle by reversing the removal steps, securing it firmly and ensuring the belt operates correctly. Finally, replace the plastic cover and test the seat belt functionality.
Replace the belt and buckle as one unit.
You have to replace the entire assembly.
I had the same problem in my 99 Sienna. I went to the Toyota dealership (Canada) and they said I had to replace the entire seat belt and mechanism ($300+). Apparently the seatbelt sensor is tamper-proof, so if it goes on the fritz, you have to replace the whole thing instead of just replacing the sensor. I'm not convinced; I think Toyota is saying that because you're not supposed to tamper with it (ie. protecting their liability), but there must be a more affordable do-it-yourself way to fix it. I have the same with my 2000 Sienna. I found a Corolla owner on a forum with the same problem and he replaced the buckle with a newer one that had the buckled-sensing switch in the buckle and wired it into the switch plug from the belt retractor. Can we do the same with our Siennas? I am going to check this out. It seems that Toyota used the buckle sensor up until 98, switched away from it for three years, and then went back to it in the 2001 models, hence the ability to replace the buckle.
To fix a broken backpack strap buckle, you can try replacing the buckle with a new one of the same size and type. You may need to sew or attach the new buckle securely to the strap. Alternatively, you can also try using a strong adhesive or tape to temporarily fix the buckle until you can replace it.
Best to go get a used one & replace it
Remove lower seat cushion by popping the front of it upward from the 2 retaining clips, then sliding it forward. The seat belt buckle is bolted to the floor.
To unlock the seat belt in a Toyota, simply press the red release button on the buckle. This button is typically located on the side of the buckle and may be labeled with a symbol. Once pressed, the belt will disengage, allowing you to remove it. If the belt is stuck, ensure there are no twists or obstructions before attempting to release it again.
I don't see how you could install just the buckle. I suggest you go to almost any salvage yard and get a replacment belt/buckle assembly. Replace the whole thing.
With some belts there are clips in the reverse side, which you can use to change the buckle. What do you do if the belt you want doesn't have clips? Well I cut the stitiching or remove the rivets, depending on which the belt has, then replace the buckle and refasten it with safety pins, or if you have a thinner belt you may prefer to staple it. Hope this helps.
The parts of a belt buckle are the prong, buckle and belt.
