A/C Heater Fan

97 Riv . Fan doesn`t blow anymore. Do I access it from under the hood or under the dash? I`ve got a replacement.

Might not be the fan at all. Could be the blower control module.

It's under the dash on the passenger side, close to the console. Larry could be right, but usually the module runs the blower full time, even with the key off.

Ouch! Thanks for the warm welcome. Like the car. Love the site.

jus messin wit ya weez man!

I also had a 82 Riv. Now that car , I loved.
I forgot. Thanks to all for the replies.

Changed the fan yesterday. Really close to the front wall about half way between the console and the outside wall. Three screws holding it in. Two easy to get at and the one close to the wall was the most difficult. Not a lot of room to work with. Easy if you have a small kid to get in there for you.

Nice that the fan fixed the problem. Watch out for failure of the blower door actuators.

Are the blower door actuators near the fan?

Excellent info. Thanks.

Hey guys, im new here and also new to owning a Riviera. I picked up a 95 s/c for $700 (not knowing it was the best $700 I've ever spent lol.) Everything was perfect at first, biggest problem is the blower motor...yes I've been searching crazily through the forum but nothing seems quite like my problem...

First all I needed to do was hit the motor with a hammer, worked full power for a week or so. Then nothing, hit it again, worked for a day. Stopped, so I (impatiently), hit it too hard and Well...it worked but it sounded like a blender at this point lol. After this happened, it worked very weak and spotty. Would turn off and on randomly. Now it doesn't come on at all (even after I replaced it?)

Sorry if I seem hasty, but being winter in Wisconsin, working third shift just really sucks with no heat, especially defrost (: .

By the way the names Garrett, 22. Happy I found the forum. Seems helpful!

is there some reason you're not simply replacing the motor? They are pricey at the dealer but not so much on-line, as low as $35 (I did a quick google search) probably because the motors (fan cage separates from motor) fit certain Nissans as well as the Riv and Aurora. Junkyard one should be cheaper still.

(EDIT: I can think of one reason - it's a tight space to work in for the install)

If the new one doesn't come on at all, first check for power at the plug. You may have fried the blower module if none is there. It could be as simple as a fuse, but this is a Riv. As Albert said, this car shares a few parts with other GM's.

Forgive me for being vague...I did indeed replace the motor with one I picked up from a scrap yard. It was 35$. Seemed high priced but it was convenient so I didn't mind. Now I am considering going to pick up the module from the same car I got the motor from at the scrap yard, if you think it'd fix er up. I can't keep driving with no defrost, pretty foggy last night + icy windshield, not fun.

Thanks guys for the replies! Great to have helpful resources ...( my local advanced auto parts is not so friendly!)
Also fyi first thing I did was check the fuses, one in the driver side dash / under rear seat.

Was it the scrapyard motor you hammered to get to work/

A new motor from rockauto.com, including the fan cage, would cost about $35 shipped it turns out. So if you have to hammer that yard motor maybe if the yard allows returns you take it back and get a new motor over the internet...

Thinking about it, a blown blower module makes a little more sense. but -- does the HVAC control head (in the dash) appear to work right? Also, let's just say if you were in there monkeying with the radio for instance I wonder if maybe you have loosened a connector behind that control head... again just sayin, don't go tearing apart the dash chasing ghosts or gremlins on my account.

I replaced the motor that I hammered , the scrap yard one seems to be okay, they told me they tested it to make sure it worked (but who knows if they did.) And yes I've put an aftermarket radio in dash, but all the control displays seem to appear normal. And when the blower did work the in dash control was spot on. Hope that helps clear up any questions I may have left unclear, thanks (:
