Hello,
I seem to be having mutiple issues this week got to 1 solved 2nd waiting and my newest all the lights our out but the temp knob now this is the analog version no display so I'm thinking about changing the bulbs if they aren't soldered on If so I'll probably just buy a used unit but I'd like to replace it with the one with a display is that possible?
Thanks

They are soldered in.. I don't know about plugging in a display one, I have an extra if you would like to try?

The display unit will not be compatible with your manual system.
The backlighting is incandescent, the indicators are LED's. Use a 2174 bulb for the incandescent replacements.

Thank you sethjamesrimrodt for the offer and thank you harofreak00 for the information, but can I ask why the display wont work?
If anyone has a working spear nondigital display I would like to buy it.
Thanks!

I think (dont know) it's because you may not (don't) have temp sensors in the air ducts, check your local junk yard

Because your HVAC airbox doesn't have all the actuators required for the dual zone climate control. You also don't have the temperature sensor for the external temp reading. The systems are not cross-compatible.
