Hi ORE, more troubles to nut out. Only two though
#1: mostly when it's cold, but some times when it's warmed up. When I put it in drive (or 2 or 1) the revs drop violently, often down to about the 200 mark then after about a second or so will reset back to just below idle (600-700). haven't noticed it in reverse. Hasn't stalled at all, but comes pretty close. When it's cold or at lower revs (1000-1400) the lock up clutch also won't hold. By that I mean it will engage, but it'll slip. And if I'm doing about 2000rpm in 3rd (D) and take my foot off the gas, the revs will drop all the way to 1000 and then rise back up again - almost as if the 3rd gear clutches slip when the load suddenly comes of them. But there's still torque if I put my foot down again.
#2: the air conditioning, fan, heater doesn't work at all. No fuses are blown but with the multimeter I can't find any power in any of the wires in the aircon harness. So not sure about this one either.

If any of you Nissan gurus out there have any ideas on what's causing either of these, your help would be greatly appreciated. Weird ones I know, but these are the symptoms I'm experiencing. Just had a trans flush and the fluid level is good, and nice clean red fluid too - not burnt.

The auto box probably needs a specialist, which I am not, so I'd say replace the clutch pack and hope that fixes it.

The aircon may well be a fusible link or faulty relay. The relays are behind the driverside battery.

The fusible link will be brown with a white/red wire after the connection. The A/C -should- be fused, and that wire is blue. I'd double check everything again, pull the fuses out to test them as you shouldn't test them on a live circuit. Check all earth connections and douse all the connectors in CRC66.

The heater problem sounds like the heater power transistor located betweed the blower motor and the a/c core. My saf had the same problem and it was the power transistor

Cheers guys,
Are the fuse able links you're talking about not in the fuse box in the driver kick panel? And I'll pull the relay and test it manually to see if it's going or not. Just weird that there isn't any power anywhere in the ac circuit.

No the fusible links are on a panel behind the driverside battery. they look like wire, not a fuse as such. if there's NO power elsewhere in the circuit that would be the first place to start.

They take a good bit to blow, so you should check that nothing's shorted to ground (ac motor, ie)
