Blower and Air Con woes!
Hi all,
i'm hoping someone might shed some light on this:
Vehicle is a 2007 tdci 90 with a truckcab (and just 8000miles on the clock)


My blower suddenly stopped working on speeds 1 and 2, and only works on speed 3.

the interesting bit is this:

at the same time the AC started acting up. It only turns on (i can hear the compressor working and the unit gets very cold) when the blower is set to speed 1 and 2.

As soon as the fan blower actually starts working (on speed 3) the AC compressor turns off and stays off.

any help would be appreciated!

Regards

Mark

Thanks for the quick replies!
Would this explain the ac compressor only working when the blower is on speed 1 &2 ?
Thanks

Ok this gets better by the minute. Took her into the main dealer here in Malta. They confirmed that the resistor needs replacing (and charged me a €19 inspection fee). But then informed me that they don't have it in stock and will take about 3 weeks to arrive.
I asked for the price o the part and am still waiting for an answer!


SO I took the Landy back, and on my way home I tried the Blower and its working on all 3 speeds! AC also working on all 3 speeds again too!

so...did the little gremlins fix my landy?

Main dealer doesn't know what he's doing?

i dunno!

but i'm really happy its working again!

AC and Blower died again!



so...back to the original suggestion of replacing the 3 speed blower resistor...

Anyone knows what the part number is ? OR where i can find the actual resistor to be able to read the part number off it and eventually replace it?

Regards

Part no for the blower resistor is - JGM500020

It's located at the back right (looking from the front) of the blower assembly.

OK So I gave the landy a quick powerwash on the weekend, and went for a drive straight after.
What do you know...Blower working and Ac working!!!!

Next morning dead again...so got me thinking...burnt resistors don't come back to life....

contrary to the Dealership's €19 diagnosis "Blower resistor must be replaced (about €40 plus labour), but not is stock so wait about 4 weeks"

today i went to a good auto electrician, he found a small grey plug just next to the resistor, opened it, cleaned the contacts and tightened them.

And now all is ok!

Thanks All!!

No if you can make it out....i only had a quick look and it started raining.

The wires in the back ground up against the bulkhead which appear to enter the fan are shagged Sad

Before I go and have anothe look can anyone confirm what I need to do to resolve....is my wiring loom a wee bit knackered - on at 6.5 years old it ain't new but surely this shouldn't be happening?

Thumbs Up
