  1. Will a 4t60E Variable Speed Sensor stop Cruise Control From working?

    Yes, correct tire size and pressure, possibly 32, as opposed to 30 on the b-pillar sticker. I am emphatic about pressures being at, but not below, sticker pressure, and regular maintenance checks done at each fuel stop. How does one check the wheel speed signals at same time as vss? Is that...
  2. PCV spring missing. Is that a problem?

    Thanks for the lead. However, I caved to the lure of replacing it quickly, at a greater cost, as my son, whose car this is, is leaving to return to his college, 3 hours from us, tomorrow evening. I don't want to cause any more damage, as who knows how long it's been patrtially installed...
  3. PCV spring missing. Is that a problem?

    I pulled out 1997 LeSabre custom's pcv valve to check, as a matter of routine maintenance. Haynes manual referred to pulling out a spring, and reassembling with a spring. There was NO spring in the assembly. What problems will the spring's absence cause? The pcv valve rattled, so it shows as...
  4. Will a 4t60E Variable Speed Sensor stop Cruise Control From working?

    Is the lower switch, at the pedal,stop lamp and cruise related? Is the upper switch cruise control related, or relatives d to antilock brakes?
  5. Will a 4t60E Variable Speed Sensor stop Cruise Control From working?

    I have looked for breaks in wiring at cruise module and found none. Connections at, and, to the module are tight and clean. I disconnected the throttle cabling at the module to inspect the yellow strap inside and found it strong and intact and connected, internally. I need to apply a multimeter...
  6. Will a 4t60E Variable Speed Sensor stop Cruise Control From working?

    1997 LeSabre Custom. No Cruise Control. I've replaced Brake Switch and the switch above the brake switch, and checked the control box cable (the yellow one inside the control unit), and still have no cruise control on the LeSabre. One forum thread here suggested that some Transmission issues...
  7. 1997 LeSabre Custom: Adding Aftermarket Gauges>Where to run the wiring?

    It's a 1997. Information is power. In my head, at 181,000 miles on the odo, it would be nice to see if she's creeping up in temp, or not getting enough oil pressure. I've been spoiled with cars with at least a temp gauge and tachometer, and he drove my car (not a Buick), which had those, before...
  8. 1997 LeSabre Custom: Adding Aftermarket Gauges>Where to run the wiring?

    Are you meaning to delete even putting in the gauges? I'm not following the thought.
  9. 1997 LeSabre Custom: Adding Aftermarket Gauges>Where to run the wiring?

    @BuickGirlFromMars: Thank you for the option. Yes, that's easy, it appears and plugs into the OBDII port. I found it online. I would like to have analog gauges that would be an easy, quick-read, while driving.
  10. 1997 LeSabre Custom: Adding Aftermarket Gauges>Where to run the wiring?

    @BuickGirlFromMars, I don't know where that may be under the hood, or the dash. Is that an actual gauge set that has directions on how to route through firewall?
  11. 1997 LeSabre Custom: Adding Aftermarket Gauges>Where to run the wiring?

    Knowing that the car doesn't have a great engine-status information system, except for Idiot Lights, and after watching a car revival channel on YouTube (Junkyard Digs), I want to start a project. For each of the revivals, which may have a minimally-gauged dash, the lead usually adds a set of...
  12. 1997 LeSabre Developed a Shudder

    Thank you two. He returned home, this past week. I asked him if it shuddered at school, or on way home, this time. He said, "Not really." He told me that there was a little shudder when he went to pick up a friend, the night of his return. Since the trans fluid has been changed, today I added...
  13. Gas gauge floats from full, to where i think it should b, back to all the way full. For 15 min. then repeat?

    It sounds like the resistor on the fuel pump is going bad. Sadly, it will likely continue showing inaccurate fuel level. Son's 1997 LeSabre shows full nearly all the time, so he clocks his mileage via the trip odometer, to know when to fill, again. The only fix that I've seen/read on other fora...
  14. 1997 LeSabre Developed a Shudder

    Labor Day 2020 I changed the high pressure power steering hose on son's LeSabre in my nextdoor neighbor's driveway. Neighbor's driveway is level, mine is a 30% angle. I jacked up the car on passenger side from the front, using the frame-rail as the lift-point, and heard what sounded like a...

    What's been the diagnosis in the last 2 weeks?
  16. 2000 Buick LeSabre - 124,000 Miles - Runs Great - ??? Car while just sitting in front of house horn started blasting in a solid sound for no reason?

    Could be the relay, but this a problem across all years and mileage of Buicks. My son purchased a 1997 LeSabre with no horn. Sellers had pulled and replaced the horn relay, after the car's horn would not stop blowing. The replacement relay, a brand new Duralast from AutoZone didn't stop the...
