98 GC blend door question

I have a 98 GC Limited with ATC. I have a blend door broken. It is showing the code for door overtravel. The AC was blowing warm, so I kinked the heater hose line and the AC got cold.

Here is my question: Do I have the single or dual blend door? I do not have the zone control on the HVAC, but read that some "upscale" 98's had the dual door. I am not sure which replacement to order, and don't want to rip the dash out to find out and then have to wait for a part to ship.

Thanks!!!

the 98 should be single blend door in 99 they went wild with the dual zone and the blend doors were constantly breaking on those. but to the best of my knowledge yours should only have the single door

search for the blend door repair on google. you can do a "modded" repair without taking the dash out
