2008 Isuzu Ascender ProblemsHarsh transmission shifting due to failed input speed sensor
The transmission may develop a harsh shift condition with the Check Engine Light on and fault code P0717 stored. This is commonly cased by a failed input speed sensor (ISS), located inside the transmission. The wiring at the sensor may be found damaged. If so, the sharp edges near with ISS wiring should be filed smooth to protect the new speed sensor wiring from damage.
The horn may not function at times due to a faulty ground circuit in the steering column. Our technicians tell us that adding a ground strap between the upper and lower steering column mounting points will commonly correct this issue.
A no crank condition may occur and the IGN E fuse is blown. If this occurs our technicians recommended 3 places to inspect for wiring issues: Under the sill place at the drivers side rear door opening, along the steering column, and near the brake pedal bracket. Damaged wires will require repair and should be repositioned and protected from further damage.
2008 Isuzu Ascender QuestionsMy ac blower won't work after replace stereo. What can be the problem? (1 answer)
I remove the stereo. And put it back. Then my switch to turn on the blower for the ac won't work
When you turn the setting up to another number to blow more hot air out it stays the same. I hear it go thru all the settings but doesn't go any faster. Could there be a heater door stuck or something wrong with the actuator?
2008 Isuzu Ascender RecallsHeadlights & Daytime Running Lights
These vehicles are being recalled because the headlamp driver module (HDM) can overheat and fail. This will cause the headlights and daytime running lights to stop working. Loss of this lighting will affect the ability of the driver to see the road and reduce the vehicle's visibility to oncoming vehicles, both of which increase the risk of a vehicle crash. The remedy for this problem is still under development and not yet available.
