Subject: Re: Climate Control Damper is stuck in defrost mode by pianoguy on 2011/6/11 2:08:59 On the LTx cars, there is a check valve that connects the vacuum line from the HVAC system and cruise control to the intake manifold. If it disintegrates or breaks, that can cause symptoms like what you describe. I think the L98 has a similar check valve, maybe near the distributor. Worth a look, cheap fix if that's it. |
