    How hard to go backwards?

    My 1989 Suburban has the high-low beam switch mounted at the base of the column with the actuator rod going up to the turn signal/wiper/cruise multifunction lever. The rod does not seem to be connected to anything at the upper end anymore, I suspect the plastic has probably broken. The switch...

    How does this sort of thing happen????

    I took my 1989 2500 Suburban in to get stuff done, got it back and its been running great. Steering wheel doesn't feel like its going to come off like a Loony Toons skit anymore, no check engine light staring me in the face, no Spyhunter level smokescreen out the back at speed over 55 MPH...

    TBI symptoms changed (new thread to reflect new problems)

    I started a new thread because the previous one where we were trying to solve random shut-offs may no longer be relevant... Over the weekend I had an out of town music job which meant I needed to run the 1989 Suburban out there (about 70 miles each way). After replacing the fuel pump relay...

    Fresh joining...

    I just signed up today - although I've been reading and educating myself from the posts here for a while. I normally have had other brand vehicles and the 1989 Suburban is the 1st GM vehicle I've owned, so the learning curve has been interesting although until last year I had a friend who was a...
