    04 TB temperature needle drifts to the right when going up a hill

    Thanks guys, the STFT runs up and down between 0 to +- 5 when RPM is constant . Sometimes it goes +- 8 and the most I've seen it was -12 but really brief. LTFT never got there. Last code I had was P0442 small leak. I just got the clone Tech2 VXDIAG tool will put it together with a PC to test the...

    04 TB temperature needle drifts to the right when going up a hill

    I am running in 3rd uphill. The cat is about 3 years old but with very little mileage since. I just tested the pressure at the upstream injector and it's 0. I don't know specifics for Trailblazer but I thought the trim should be plus or minus 5% or at the most plus or minus 10%. What else should...

    04 TB temperature needle drifts to the right when going up a hill

    I just drove it right now at 88 degrees outside temp it started out at fully warmed up on the streets 198 to 201 the 201 was at a light then I got on the freeway and went down to 195 and ranged between that and 198. As soon as I hit a small hill of lets say 1/4 mile length maybe less it went to...

    04 TB temperature needle drifts to the right when going up a hill

    I think I was referring to relay 45 and the white wire contact at the relay which is the middle of the 3 prongs at #4. #5 is from PCM and #2 is from the fuse. When I check with test light I get + on 2 and 5 but negative on 4. So my question is for the fan to engage doesn't the relay have to have...

    04 TB temperature needle drifts to the right when going up a hill

    It went to only 800 or so Fan Speed which is low I did have the Autel opened at the fan readings. So jumping 2 and 4 did not provide the full blast airplane noise. Maybe the harness is not making full contact or the fan is bad. I didn't check resistance as TJBaker57 mentioned between the black...

    04 TB temperature needle drifts to the right when going up a hill

    I just changed the fan clutch again and took it on interstate 5 going toward Magic Mountai there are a few hills nothing major and it went up to 126 with or without the ac on. Turned to 90 degrees to engage heater and it just stayed at 123 but not lower. Last year with load in 115 when I turned...

    04 TB temperature needle drifts to the right when going up a hill

    SO usually it was during the day 100 degrees outside. The water pump thermostat and temp sensor are all less than a year old also the fan clutch is the same, all ACDelco except the fan. Last year I pulled a boat to Laughlin and it went to 3/4 had to turn air off and heater on on those hills but...

    04 TB temperature needle drifts to the right when going up a hill

    So I replaced the electric fan last year together with the thermostat and temp sensor right next to it. I did this after coming back from Laughlin pulling a boat and it caused it to worm up with the air on going uphill. Had to turn it on heater to go up those hills. Well now I want to go back...

    SOLVED! 04 Trailblazer battery light issue

    I first found and repaired the red wire on the alternator connector, it provides the alt with power to start charging the battery, so that fixed the gauge and the charging and I also found and repaired the black wire and that fixed the battery not charging and red warning battery light. Pretty...

    SOLVED! 04 Trailblazer battery light issue

    OK here's the diagram, so I don't remember which one I fixed but I think the field duty cycle grey wire not the red one. I also have not checked fuse 24 which is 10A. Very strange that the gauge shows 14 but the message center and the red light are on. The alternator was not on the car when the...

    SOLVED! 04 Trailblazer battery light issue

    So I did some work on the cooling system, had to remove the alternator and because I didn't disconnect the battery negative I touched the wire that goes from the alt to the battery against some ground it sparked and when I put everything back the alt wasn't charging the battery and I had a...

    04 Trailblazer low power feels like it's plugged up, scary trip back from tahoe-HELP

    That's what I meant, sorry for the typo, I did order the O2 removal tool and it should be here any day now. I drove it around and it seems to have slightly more power but not much. Still lacks power and it keeps the RPm above 2k most of the time when picking up speed. I haven't seen any new...
