New To Me 98 Tahoe, Green

Not wild about that other site. Not sure what it is, but I get a bad vibe somehow.

Got it pulled apart and I see the clip.




I pulled the two screws and removed the Trip Odometer. I sort of see how it works, but when I rotate the shaft by hand, the same thing happens. It gets stuck at 9.9 and won't roll over. UNLESS, I apply a slight bit of pressure to the back of the number wheels. Then it flips and keeps counting. Not sure what's going on there.


Edit ... on close examination, the black gear wheel closest to the red clip (left of the 3-4 in the picture), the drive gear wheel if you will, has a small crack, enough to make it loose on the drive shaft. A drop of E6000 hopefully will resolve that. If not, hopefully I can find the Trip Odometer as a separate unit somewhere.

HVAC Control shows no signs of anything being too hot. Blower operation seems inconsistent, so I'm guessing the motor since it's rather noisy. They don't appear to be overly expensive, so I may just go that way if they're not too hard to replace.

By the looks at what's going on there, you may have the lowest mileage truck of all of us, when the job is done! Lol

Trip's back in. Ran it several times by hand and it clicked over to 10, 11 and beyond every time. Wednesday will be the drive test.

Is this really the blower resistor, tucked in there on top of the box?



Looks fun to pull out.

Does this tell me anything useful?





Is there a decoder here for each 3 character alpha/numeric segment?

Yes. Blower relay to the left.

 

[OR VietVet]

Relay there and the resistor will be mounted so that the heated part of the resistor will be inside the blower housing so that the air flow from the blower can cool the resistor.

Trip counted up fine today. Didn't fully reset to 4 zeroes when I filled up with gas, but I may not have pressed it fully.

Second full tank of gas and I'm barely pushing 14MPG. All two lane rural roads (50-60MPH, some hills but not many) and some city driving.

Reasonable, or do I have some issue?
