I’ve been trying to locate the EGR pressure sensor on my truck listed above SD. I already have the new part but can’t seem to find where it’s located to replace it.

Hello GHOSTCOOKIES,

It should be on the firewall. I have added a picture for you. Looks like it's behind an intake pipe possibly in the center.

Thank you,
Brendon

A/C stuck on defrost and floor. I'm looking for the heater vacuum control manifold. (Under the glove box?) Vacuum lines have been checked.

Hi,

I believe you are referring to the vacuum control switch. That is the component that is adjusted to change the airflow direction mounted on the dash.

I attached two pics below. The first one is the vacuum schematic for a standard unit. The second schematic is for a dual climate control system. I'm not sure which you have, so I attached both. Also, here is a link you may find helpful:

Let me know if this helps or if you have other questions.

Take care,

Joe
