When I push 4x4, the yellow 4x4 light flashes continuosly. No 4x4
I hear the xfercase shift motor when i push the button. Sounds normal
Pulled the plug out of the front actuator... I get 14V at the brown wire all the time wether it's in 4x4 or not. Fuse in the dash side panel is good. Are there any other fuses?
Only wrench in this is a possible wire/connection problem when the truck was repaired. I followed the harness from the actuator all the way up. Everything is connected. I checked the xfer case. Everything is connected. When i disconnected the xfer case plug, the service 4x4 light came on. Figure that was normal. Restart reset the light.
The question is this... what is the most likely problem? Actuator or xfercase switch?
Will the new style actuator I put on my wifes 94 Blazer (Full Size ClassicK) 26060073 fit as a swap test? Looks the same.
Are there other voltage readings I can take at the actuator plug from the other three wires to be sure it's getting the proper signal.
Also... maybe it's not up front at all? I was reading in the si2000 (GM Service CD) that the xfer case looks for the front axle to engage before shifting. Is that true? My si2000 always refers to the Autotrac case. I'm not sure if only the autotrac does that.
I have the option of taking it in to the dealer. I have extended warranty. Just like fixing things myself and not having to come up with something to drive while it's there.
