No, it has the what the service manual calls the IPM (fusebox), but not a TIPM.

Ok thanks. Guess I'll get another. So at what temp is the fan commanded to do anything?

To me, it behaves like there's a cracked/broken solder connection on a circuit board somewhere.

The thermostat is an OEM Cummins 190, replaced once since the truck was new, and the temp gauge behaved as the original prior to this AC/Fan issue. The temp didn't climb as it does now prior to opening, nor did the temp increase when climbing hills, especially unloaded. Right now it reads just...

Filled by weight, as prescribed according to the tag under the hood. Bottle on the scale, etc.

Backstory- 2004.5 HO Cummins owned since new, Smary Jr. level 1, 138,000 (I think) miles, basically a cream puff, no other engine/trans mods that I can recall offhand. A few years ago the AC stopped being cold. I read Tuesdak's threads and many many others around the internet and this forum...

True enough. That "low charge" state though is still high enough to cool the driver's side as normal and the passenger side is getting lukewarm, but I do agree, with all the electronics, it could cause wonkiness. Like you, my buddy who recharges my truck says a compressor seal may be slowly...

I suppose it could be a very slow compressor leak, unable to be detected, but I don't know how that would affect the fan behavior. I could very well be dealing with compound issues given its age.

Yes, the system was evac'd and recharged to the proper spec after the fan clutch replacement. Yes, the oil has been changed since all this was done, and the new filter has no A/C oil coating it. When I left work tonight (a few hours ago) I turned on the AC and drove slowly away- no morning...

Wiring is good. The replacement fan clutch is Mopar OEM- Vistronic if I'm not mistaken?

I should add, the truck is still a cream puff. It's had a great life, only 125k miles, no wiring chops, added goodies, Smarty Jr. has only ever been on fuel economy, etc.

We did a refill/leak check before I replaced the fan clutch and the entire right side of the engine was yellow and the oil filter coated. That's how I diagnosed the fan clutch. There was nothing visible or detectable. The only loss was out the relief prior to the fan clutch replacement. I...

OK, so it seems like my problem is back. The passenger side vents have gone warm again so I know I'm losing refrigerant. The truck doesn't have morning sickness (it did when I replaced the fan clutch), but maybe that's due to ambient air temp?? The engine temp rises over 200 (probably 210ish)...

Just to follow up, it seems to be working great. The only other problem I have is that all my HVAC doors move slowly. I have removed the motors and tested them and they seem to have a mind of their own. If I move the knob, they sometimes move, sometimes not, and if they move it's slowly. I...

10-4. Should I just vacuum again and do the recommended fill on the tag? Thanks.
