I have a small issue with my wind shield wiper

I drive an Isuzu Rodeo and I'm trying to sell it. There is a small problem that I'm trying to fix since small issues often bring down the price of a car alot. With the front windshield wipers when you put it on the 1st degree automatic, which is the slowest and has the knob to control the speed,the wipers go up a little and get stuck. They don't move at all ever again, not even back down. So to correct the problem you either have to put it on degree 2(medium speed) or degree 3(fastest) to get the thing going. On degree 2 and 3 it works totally fine, no problem. It's just the 1st one that gets stuck. So I'm guessing it can't be the gears or the motor. My dad suggested it's something with a fuse or something related to the electric box. Help? =D

I doubt it's an issue with the fuse since the same fuse would be used for the other speeds as well.

You don't mention what year your Rodeo is, so I'm not sure of the configuration. Is the delay controlled via a knob at the end of a stalk? Is the wiper stalk a separate stalk from the turn signals? What happens if you wiggle the stalk? How about if you twist the delay knob a bit, not enough to go to the next speed or off, but just enough to see if it causes a change?

Something similar is not uncommon on Ford products. The affected Fords have a rotating knob on the end of the turn signal stalk to control the wipers and delay. Inside the knob are contacts that get dirty or worn over time. A reasonably reliable fix is to pop the screw cover off the end of the stalk, disassembly the delay switch being careful not to misplace the detent spring, clean the contact, apply new switch lubricant, then reassembly.

I suspect the reason the wipers don't park if you turn off the first setting is because they have not traveled far enough to get away from the park switch. What happens if you turn to delay 2, wait for the wipers to reach their top point, then turn back to delay 1? Will they continue their pass? If you turn them off about halfway down the pass, will they park fine?

A new wiper motor may be required. As mentioned above, the electrical contacts in the existing motor may be worn or dirty.

IMO, replacement of the motor may not increase your sale price enough to cover your costs.
Isuzu Rodeo resale value is quite low, because:
- it's a discontinued model,
- Isuzu has announced a withdrawal from the US market in six months
- All SUV sales are depressed due to gas prices.

Many older cars have some idiosyncrasies. Given the wipers work in all other positions, it may just be easier to be honest about this problem and advise the buyer simply to not use the slowest wiper position. Realistically, it is a minor problem (so far) and is not much of a concern compared with the other problems associated with buying an Isuzu.

Well the tires also need to be changed and there a few other small things too. I'll see the connections and see what that does. By the way my model is a 1999 LSE. There is a stick on the left for signals and light and there is a signal on the right for windshield wipers and cruiser.. I believe that no matter what when you change it back to setting 1 it gets stuck. I'll go check on it.
