| I have a Brother and Sister in law who have a 97 Riviera. I don't know any other details such as engine and options yet. Apparently it has an A/C problem where the A/C cycles off and on. I think from what they said that vibration and a loose connection, ground or relay somewhere is the problem. They live in the Phoenix area and I live in Kansas; however, I'll be headed out there tomorrow. Lucky me! I'd like to know if there are any common Riviera issues I should look into first. Also, where can I find a wiring diagram that covers this system. I've never played with a Riviera before and don't know the geography as to location of relays, fuses, etc. I think they have an owners manual; but that's about it. Any help would be appreciated, thanks. | |

| Keep in mind that it is quite normal for the compressor to cycle on and off, if that's what they mean. But follow AA's link for more info on other issues. | |

| Hey Bruce: I don't know what your route is going to be going to Phoenix, BUT...if you're gonna be on I-10, I live in Deming, NM. and I have the dealer service manuals that I will be happy to let you take a look at and if you will be coming back though here on your way back home, you are welcome to take them with you and just drop them off on your way back. Just a thought...  | |

| We flew here from Wichita. I have taken a look and it appears the blower isn't running at all. I figure I should be able to make it run on RECIRC or some setting on the control panel. I've been using the block diagrams provided by AA in the link above. I checked all the fuses in the block by the drivers door and all are good. I removed the blower and blower resistor. There is no 12V going to the blower connector. I'm guessing it has to pass through the resister. I can hear what sounds like a relay clicking; and I can see the blower door opening with the blower removed. The blower meter turns freely.
I checked the resister with a meter, but don't know what values I should have between the 4 pins. Here is what I have in case anyone knows. (Note - contacts are not numbered - there are two areas that the two plugs from the car go to. One area (the smaller one) has only one pin - the other area has 3 pins.
Red wire (contact to small connector) to Purple wire contact in big connector is 0. .9M ohms.
Black wire (contact to large connector) to Brown wire with black stripe in large connector is 6M ohms. Everything else reads open.
Also, the pin the purple wire connects to reads a short to the case of the transistor.
BTW the motor reads about 1 ohm when not turning. If I spin it by hand the value changes some.
That's what I know so far.
Thanks for the offer Dave - that's very nice of you. Since my time is limited, I think I'll pass for now. | |

Didn't notice that you're already there. However, I will be in Tucson later this evening and I can bring the manuals with me if you want to come down there. I will be at the Triple T truck stop on I-10 about 8:00 pm. I will go ahead and bring them with me just in case.
