Two months a go I replaced the blower module and blower motor. Everything was working GREAT. Now, today when the heat was set at 85-90 degrees cold air blew out of the panel and floor vents and i noticed the compressor kick on. I switched to vent, compressor went off, switched back to Panel&Floor mode and the compressor kicked on and got cold air. selected Floor only and the compressor kicked off...all-the-while temp was set at 85 degrees or above. If I select defrost I also get cold air. Only selecting Vent and/ or Floor will compressor kick off.

Any ideas? Thanks!

Vent is the only setting where the A/C won't run, all other modes it kicks the A/C pump on to dehumidify the air.

As for cold only, was it like 100 degrees where you were, and it needed to be colder? If not, start looking for "blend door", my guess is that yours is broken.

Good luck.
