After 3 alternators, all remanufactured I might add, I went to a local auto electric shop and had a new alternator ($330.00) put on and all troubles are gone! From what I was told all remanufactured alternators have voltage regulators that are not up to par as reman alternators have bad voltage regulators in them. On the Rodeo and Passport, the voltage regulators are grounded to the Engine Control Module. The Heater/AC blower is also grounded here also, so when the alternator is not charging, the blower doesn't work.
On the right side of this type of alternator, there is a plug connection. The alternator has the "male" terminals, while the "female" terminals are from the vehicles electrical system. One of the "male" terminals, known as the "C" terminal, connects the voltage regulator to the ECM (engine control module). As stated previously, in remanufactured alternators, the voltage regulators appear to be faulty, a problem that has been in exsistence since the 1980's, whereas the voltage regulators do not emit the proper voltage.
While I did get all of the remanufactured alternators from Advance Auto Parts, they obviously do not remanufacture them, so it is not really Advance Auto Parts blame, however I wonder why they continue to sell them, as a recall has been previously issued regarding this problem.
I am confident that if the alternator for these vehicles are replaced with a completely new one, not remanufactured, this problem should cease to exsist!
Also, below is a link to the electrical diagrams for Rodeo/Passport.

My 96 rodeo started to overheat after the valve cover gasket was replaced. Never had a problem with overheating before. Mechanic worked on it for 4 days trying to get the air out of the system (BY burping it). Installed new thermostat, couple of heater hoses,flushed the radiator but no change. When the engine cools, you can hear gurgling noise from the 2 main hoses around the thermostat and the one out of the thermostat feels cooler than the other one. I Would appreciate if anybody with similar problem and the right way to fix it could respond. Thank you.

Hey folks! My back up lights in my Rodeo 95 stop "working" and I don't have any idea where to locate the fuse or relay to exchange it! If someone knows where to look for I'll appreciate that help! Thanks, Pablo.

Hello Pablo! I had the work done at an auto electric shop here in Columbus, Ohio. The mechanic ordered the new alternator for me and put it on! He stated that this has been an ongoing problem with these cars since the 1980's. Use the following link to contact the mechanic and reference Doug Brown (me) and Im sure he will talk to you. He was a really nice guy and knew what he was talking about!

From the noise you describe, it sounds as though your alternator belt is gone. Your alternator has a pulley, as so does your air compressor, water pump and Power steering unit. My alternator went out and prior to it doing so, it squeeled badly and then the belt broke.
If you don't know how to "move stuff around in there" to replace the belts, have a mechanic do it because it can be overwhelming to the unfamiliar. In the event that you find out you have a bad alternator, replace it with an original...not a remanufactured one. See my previous posts on this forum regarding the alternator issue!

If your's or anybody's 4wd is still out action as of April 2008; I have the most likely solution for you.
First, I recommend you have a professional mechanic perform this task unless you are tech savvy enough. But just recently I fixed the "non-operative" 4wd on my 2000 Rodeo. Your problem is definately the 4wd actuator, on the front axle. It is behind a large, black steel plate which must be un-bolted and removed; along with the smaller skid plate. What needs to be done is to remove the actuator (housing cover only) and check/clean any corrosion on the sliding, crescent shaped terminals. Basically, the actuator works perfectly, it is just that lack of use allows corrosion to form on various electrical terminals; and the motor simply isn't receiving enough of the current when you depress the 4wd button.
IMPORTANT - make timing marks everywhere - because you will have to remove a large plastic gear or two. The actuator will not function properly in the end if you do not. Note - do not un-screw motor itself, you must start your timing marks from its long plastic spindle.
Next, after re-assembling the housing, unplug the cable that powers the actuator and clean the metal terminals with a long piece of custom cut eraser (preferably a bit of a white one, cause they leave behind no residue). This can be done with a small sharp knife.
Finally, if you have put everything back together properly; the 4wd will work. You must be moving for it to engage. Turn the wheels as well, to assist the process. Good luck.
#2178 of 2315 97 isuzu rodeo keyless entry battery change issue
May 03, 2008 (3:11 am)
I changed the battery of keyless entry, but it cannot activate the door lock any more. It looks like the keyless entry is energized by the new battery for the flashing light when you push the keystrokes.
What shall I do? Thanks a lot!
