Question power steering module

I have a 96 sport v8 that has the module behind the glove box. I have a 96 lx with a v8 that there is no module behind the glove box, instead there's a port that says evo/arc test. I've searched h the site and have found nothing. What is this port and where is the p/s module?

ARC/EVO test is the scan tool hookup to test the variable rate steering.

Are there any other loose connectors under the glove box? It should be there on a 96 as they were moved there vs. under the rear deck in the 95 and older cars.

The module itself is not behind the glove box, it is under the blower motor.

Good catch...

...If what you're looking at is behind the glove box it's likely the blower controller for the SACT, if the other car has the manual climate control that controller wouldn't be there.

It's just my 94 feels tight and the two 96's feel like I have full assist. I've rebuilt the whole front end on the lx so I want to check the module. The sport has the glove box removed I just loosened the other one I'll look lower in the lx thanks guys.

If you unplug the orifice on the pump it will automatically default to full assist.

Does the 1996 - 1997 T-birds have that weird steering pump that makes steering harder at freeway speeds? Those pumps are pretty darn expensive, right? I think my 1996 SHO had the same thing. My steering started to want to lock up during very slow manuvers like pulling into parking spaces, all of a sudden the steering would lock and then sort of let go. Needless to say, I got rid of this car because a new pump was like $600.

Nah, I paid around $100 for a reman. last year, plus a $40 core charge. The pump is the same among 94-97 4.6 MN12 and all FN10. But yes, it's speed sensitive variable assist: low assist at high speed, full assist at low speed, and full assist during abrupt maneuvers.

If you order a new pump these days, you have to put your valve in it.

Save those valves!

What are symptoms of problems with the variable assist power steering on a 1997 T-Bird sport? I rebuilt my entire front suspension last year, and my front-end now feels tight, solid & the ride quality, especially over bumps, is excellent (I used all high-quality Moog and TRW components). However, I've always felt that my steering doesn't feel quite "right" - but only when driving on the highway at speeds of, say, 55 and above. When I drive my T-Bird on the highway and make the small steering corrections one must make while driving, it feels like my steering is too "tight", and that I have to exert enough force to overcome some friction or sticking ("stiction"?). At other times, my steering feels very tight, like I'm driving at a low speed and have no power assist. I've also noticed my wheel doesn't return to center after making a turn as strongly as I feel it should. I've had my car aligned 4 times since last year (not specifically for this issue), but I haven't noticed any change in these symptoms. Could these issues be indicative of a problem with the variable assist? Is there a way to disable the variable assist so I can see if that makes any difference?

Thanks,

Dennis

Has the power steering system ever been flushed? I might start there if the answer is no.

You can disable the EVO module by unhooking the harness at the pump module; it will default to full assist at all times.

I am going to give that a try soon and see if it helps with my symptoms.

Thanks!
