AC compressor doesn't engage on blower setting 4

[colinnwn]

Hey All,

 

My manual air conditioner works normally on all settings except blower speed 4. On blower speed 4 the blower works, but the compressor disengages. I've looked in my service manual and it has no troubleshooting for such specific problems, and the only thing that seems like it could cause this is the fan speed switch. Does this sound reasonable?

 

When I was looking on the Courtesy Parts site, their parts search for the control unit was messed up. But I couldn't find a fan control switch listed, only the AC base unit for $17. Is the fan control switch and the temp selector switch not separately purchasable, and does this sound like the right part? $17 seems too cheap.

 

Does anyone have better directions for removing the front panel bezel, like the ones that sometimes come with aftermarket stereos from Crutchfield and the like? The service manual directions are pretty poor.

 

Thanks.
