Question about Hyundai Motor 2003 Elantra
I started having problems with the electric door lock (controlling from driver side) sometimes it will unlock or lock the other doors, other times it won't. Around the same time the control that directs the flow of heat/ac from floor, to vent , to defrost etc quit working. Do both of these work on a vacuum system? Could the problem of the two be connected some how? How do I go about repairing them? Thank You, Rick
Not vacuum system - electrical motors move the vent doors. Without looking at the vehicle myself, the possible causes are numerous (although you mentioned you've already checked the fuses), this sounds like a fuse. Anyway, go to www.hmaservice.com and register vehicle by VIN #. You'll then have access to shop manuals, service bulletins, wiring diagrams, etc. about your vehicle.

It does not hook to throttle body , it hooks to a vacumn port on the intake manifold. Follow hose from cruise control module to the tee-three-way connector on firewall. Over time the tee will fall apart and will leak One hose goes to the vacumn port, one to cruise module,one to ac contols.

SOURCE: no air flow from ip vents.
There is either a problem with vacuum to a actuator for the blend doors or a vacuum problem to the a/c programmer.It is also possible that the a/c programmer "control head" is bad.
