Blend door actuator?

OK you are looking for cold. With it being winter I figured the opposite and you were looking for heat. You must be out in the southwest. In my area AC is not even on the radar yet.

In that case it is not a 20 minute job. The dash has to come out, the AC system has to be disconnected, the heater core drained and disconnected as well. Then you can remove the entire heater case. The actuator for the passenger side is on the back of the case.

Adding R134A will do nothing. Both sides use the same heater core and AC evaporator. The doors inside the case determine if you get cold or hot air by directing the air through the appropriate path. As you have cold air at the drivers side the AC is working good, just isn't being directed to the passenger side.

If one of the blend doors was removed it is even more work as the case has to be split to replace the door. While it is out and split I would probably replace the heater core and the evaporator, they are 18 years old and probably getting thin in spots.

If it was me and I was thinking of doing the repair myself, I would be very tempted to visit a you-pull-it yard and get a complete replacement heater case assembly from an identical vehicle. This would give you a practice run for your own vehicle. Test everything on it. Replace the heater core and the evaporator and make sure all is OK. Then tear apart the car you have, you could then save some time as you would remove the one you have and install the "new" one.

If you take it to a shop you will get it returned faster but it will be expensive. Your call on that. One advantage of a shop is that if they do the job and the dash rattles or the system does not work right, they will repair it.

Good luck

Strange, The unit uses the same core for both sides, shouldn't have changed it. But if it works and you have cold air then good job.
Here's hoping it stays that way. I'm still waiting for AC weather here. It was a whole 42 degrees today !

Please let us know what you find so it will help others.

Hello,

The heater core job and evaporator will take 6 hours according to the manual. You will need to do the a/c vacuum down and recharge, here is a guide for that.

It looks like there is two electronic and one vacuum operated.

Sorry, the system does not work that way. The actuators control the doors directly and are in different locations on the HVAC box. I do know of people who have decided they do not like the electric units and have replaced them with cable controls. But that is a bit extreme.

Well it is your vehicle. I would much rather have things controlled with cables myself. I do not like all the extra electronics myself. Have a great New Year as well. Come back with any auto questions.
