Rear A/C fan

[Rodd]

I checked the forum and couldn't find and a/c section so I posted this here.

The rear a/c fan on my suburban is stuck on high. I try with the front controller and the rear controller but nothing works. I didn't think to check the fuse but I would think that would prevent it from running at all. Is there a relay for it that could be the problem?

I'm pretty sure there is a high fan relay for it on the rear evap housing. I'll check my manual later to make sure though.

Yes there is a relay pack on the rear evap housing and it is a PIA to get to. This thread gives you an idea of what it takes to get there. The relay pack is sitting on top 2' in front of the fan motor. Yes, you have to pull the side cover off to get there, including the rear seat belt. At least for 1995.
