#7 of 10 PO442 CODE by SSG402MP Nov 25, 2008 (2:15 pm)
I have been fighting check engine codes for a year now and need some help. I have a 1998 Jimmy. It had a PO446 code for the longest which we replaced just about everything we can think of. We finally replaced the Charcoal canister and now we have a PO442 code. We smoked the system and found a small leak at the canister hose. We fixed that and it is still coming back with the PO442. Any suggestions? Thanks.

#10 of 10 1994 jimmy 4x4 switch no power by ron_a_tron Oct 05, 2009 (8:37 pm)
My wifes 94 jimmy had the transmission and transfer case rebiult a year ago, all was fine. 4x4 was engaged approx 10 times over the winter. a few months ago the rear wiper started to act up, and then lost all power. The rear wiper and the 3 way 4x4 switch run of the same power ( this is only my guess). both lost power at the same time. Where do i start ? thinking im going to try and feed the 4x4 switch with a power or test for continuity.
