Hi guys, I don't mean to over-post and ask the same questions in multiple threads, but just this once it seems like it might be helpful (mostly to me...lol), so please forgive me but I have to put all the symptoms in one thread.
Ok, I just got this rig... which is a V8 350ci TBI conversion (97).
Currently the oil and temp gauges don't work, the cruise doesn't work, the A/C clutch doesn't engage, and the air flow is stuck in defrost.
The cruise I think wasn't installed, or at least I only find one linkage to the throttle that I can see (the pedal).
Now I realize there is every possibility that all of these items just happen to be individual problems. The conversion appears to be well done... not hacked. There are fresh vacuum lines through most of it, wiring is in harnesses...secured...mostly clean with no "bypasses"..etc.
Point is, it looks like someone tried to take the time and expense of doing it right. It's not just motor hacked in there with a fuel line running through the interior of the van to the tank, and cobbled together electric...etc. I've done conversions on other vehicles, so I can appreciate the work and the thought process behind it.
So there's a couple ways to look at this. First, it seems unlikely that the installer/converter would just "forget" to hook this stuff up, or hook it up wrong and let it go (40k since the conversion).
On the other hand, it seems like a lot of related stuff (two dash gauges : A/C compressor *and* diverter box) going wrong at the same time after what was relatively recent and major attention put to the motor and vehicle.
So my question is... is there one, or two sources that would cause 4 problems (ie...a fuse will take out several things, or a single faulty harness plug)?
Because of the nature of these problems combined with the recent conversion, I'm trying to see if I need to start "upstream" looking for a different point of failure as opposed to possibly trying to fix 4 individual coincidental failures (oil/temp/diverter/ac).
I have already jumped the connector at the condenser (or is it the dryer?)... (top rearward pressure switch on silver cylinder) and the A/C clutch did not respond on max A/C.
I did this thinking possible the refrigerant is low/out because *that* is something that will happen when doing a conversion... maybe they never recharged it...etc., but I couldn't force the issue.
Again this points to an "upstream" problem (ie...no point in the next step being testing for a bad clutch), and I decided to stop there and ask so that I'm not diagnosing all of this in the wrong direction.
So.. fuses... main relays...sub computers...ignition not getting to some "area" that would affect several things at once?
Ideas?
