Default SL1 99 - Installing AC on a Saturn that never had one.

So ya I'm in FL and I have a 99 SL1. It is from Maine and has no AC. It blows air and has heat. How much would it cost me to add in a remanufactured AC system?

Something like this or is it missing key parts?

The compressor kit is only one part of the ac system. Did you consider all the wiring needed, including the hvac replacement control panel, wiring from it to the blower and pcm that controls when to power the compressor, compressor wiring to the pcm, wiring for the combination low/high pressure switch to the pcm? In addition to this, did you overlook tearing apart the interior to remove and replace or add the evaporator coil and the condenser coil with all hoses for the ac system? This wouldn't be considered an average diy project.

Perhaps examining a junk yard SL with ac may help you visualize how large this project is. The cabin hvac box holds a heater core and evaporator coil. The fittings thru the hvac box on the firewall holds the thermal expansion valve where the two ac hoses connect - one returning to the compressor (suction line/larger diameter hose), the smaller diameter hose goes to the filter/drier hung off the side of the condenser coil. One hose between compressor discharge port to the condenser coil.

Even if you did manage to install the parts in the A/C system, you wouldn't be able to use it. It would be like adding cruise control to a Saturn that didn't have it. You could install all the parts needed, but you'd still need a dealer or a GM tech 2 to enable the A/C option in the PCM.

^ Interesting point. If everything was installed correctly and a temporary setup were performed to bypass the hvac controls to power up the compressor with a full charge of refrigerant to ensure the ac system actually runs and cools, this allows a complete system test regardless of pcm interaction. The next step would be trying the hvac controls to turn on ac - the power on signal is passed to the pcm that sends a signal to the ac relay to power up the compressor. Presuming all hvac wiring is installed correctly, either the pcm turns on compressor operation or not. Again, presuming all associated wiring is in place, if the pcm must be enabled by GM, either pay GM to enable the pcm to control ac operation or find a used pcm from a car with ac.

There are many what ifs to consider when attempting to retrofit a non ac vehicle with ac............

Well, that is an interesting question.

No idea how it actually works, but it is possible the signal through the PCM will be sent regardless of whether the PCM is coded for AC or not. Possibly the difference is that a PCM coded for AC would "notice" the signal pass-through and turn the fan on (if over ~40F) plus bump the idle speed a touch

I agree with what fdryer said, best bet is look for a complete SC1 with AC and pull what you need (and hope the parts work) . . . which might include PCM

The diagram in this thread is not for a Saturn but the layout of the AC parts is purty darn close - does not include the inerior parts you will need
