## Questions & Answers

**Q: Will this work on a 1989 Wrangler instead of the cable type replacement for the vacuum actuator? instead of the cable type**
A: Don't now

**Q: Do you have just the gasket**
A: Sorry no the gasket isn't serviced separately.

**Q: See picture of broken in half? Who DO i know this wont happen to me? and what kind of warranty do you offer with this?**
A: Mine pulled apart at the rivets and ended up replacing the rivets with some small nut and bolts and it’s held together fine...of course you shouldn’t have to do that but I didn’t want to fork out another $100

**Q: Will it work on a 2019 RAM 1500?**
A: I installed mine on a 2017. ..usually the part will give you specific years…it was simple to do and saved me..about $900 bucks labor from the dealership

### ⭐⭐⭐⭐⭐ Review
*by R***W on 17 February 2026*

Update: Ram 2020 Limited 1500. Updating in order to be fair, Actuator was not the issue. I had an Electrical issue, therefore the actuator was not getting power. Actuator fit perfectly and worked fine. Did not work out of the box. Hooked it up and was checking it before I installed and it did not work. I checked the plug and all 4 wires are good, ground is good and etc. It is getting all the signals it should get but still nothing.
