Pushing the 4hi button results in only the light blinking and then returns to 2wd. No sounds, clunking or anything. Fuse #24 (FWD) is good. FWD actuator replaced. When bench testing new and old actuator w/12 volts, it don't activate. Where do I look next?
Also, half the lights on the factory radio don't light.Slowly wentout one or two at a time, over about a years time.Common? Repairable?

Go to Ebay find OEM radio and replace, cheap and easy.

Check and see if there are any DTC's present and report back so we can assist you with the 4WD trouble, is the "4WD service" light illuminated?

And also check all fuses in both IP and underHood fuse block with flashlight to see if any are open.

can the actuator be activatedby a jump wire to test if so how there are two
wires what are they for

You mentioned the actuator was replaced. Was it replaced the original thermal actuator or is it the solenoid type?

johnrob

it was bought at murrys auto parts I think it's soleniod type
whats the difference? can it be tested ?

I said solenoid but it is actually a motor. With the original thermal type actuator, the colder it would get outside, the longer it takes to engage (4WD light flashing). With the motorized replacement, the unit engages pretty much instantaneously. See TSB # 76-43-010. I don't have a test procedure for you but the TSB does have some info (schematics etc).

From what I understand, you can also ground one of the pins on the OBD connector, can't recall which one at the moment, and the switch lights will start flashing a code instead of just blinking off and on.

It looks like TSB #43-76-01A...Typo ?
