As post states, did my pcv, rehosed and all......dont think I nicked or FD anything up while moving parts around. But air output from fan is lacking luster?

Any ideas or suggs.?

Is your engine temp normal, overheating? Is it kicking in and out? or on all the time? Are both turning? Or does it just seem like theres less air moving, and there's no problem yet?

There is very low airflow thru the vents. Its heating up, normal temp, will still blow hot when on....just seems like its limping through it or blocked?

Does it work with the fan on high?

Ok, first off listen to the blower motor to see if all the fan speeds work? If they are, move on to check and see if your venting is working properly, check the defrost, floor, vent, def/flr and see if it's directing the flow of air to the selected position properly. Also, check to see if the recirculating air/fresh air function effects anything. If everything seems fine, I'm thinking the vent which initially opens when you turn the system on, isn't opened all the way, and not allowing max volume of air from the blower out to the selected vent. or maybe something broke in the venting, and the air is escaping there. let me know

Yeah, Im done teaching for the week, so...tomorrow i will have time to get on it....think its something stupid and smal....also gotta do Fn knock sensor tomorrow

Lower hose cold to the touch...prob check or just replace thermostat......hoping its fuse, or something.....gotta spend more time tomorrow and hoping its not fan motor!

Try feeling the top rad hose to see if you can feel thermostat open once it hits operating temperature, also i would think the temp gauge needle would take alot longer to reach normal temp if it was stuck open, or opening early.

If this is after letting the car reach normal operating temperature, then the thermostat needs replacing.

Yeah, its cold after reaching full temp....fan speed does not affect flow through vents.

18" of snow........dissecting the fan issue....foggy as hell, nothing seems to be amiss....the, all of a sudden Nail huge pothole I always avoid, and the fan starts blowing like crazy!?
Problem solved?! At least for now, its working on all speeds!

^ i dont get what thats supposed to mean!?

Knew it was too good to be true....its cutting out again...must be a Fn short

What exactly is cutting out? The blower motor?

mikehammond

The whole time I thought your fan speeds were working? Check for bad connection at blower motor, if not connector issue. REPLACE blower motor!!

350zMaximaownr

Haha, no....its gotta be a ground at the blower, I am going to reground everything, clean. And possibly just upgrade wiring.....it keeps intermittently wokring, then major pothole and it stays on....so, blower motor possible, otherwise, time to clesn up grounds and check electrical chit.....thx 4 input
