Trouble shot my daughters 2000 NB for several issues… first no a/c, blows hot air , no lh brake light , drivers window slow to go up and reverses, rear hatch won’t stay unlocked when button pulled and finally thumping when stepping on the brakes…..
The no a/c. ended up being a couple of issues ,
first …..no fans with ac switch on, speed on #1 and key to on position, checked for voltage at the compressor with engine running and had 10 volts . Next I checked the ohms on the compressor clutch 3-5 ohms….
Started with Dans trouble shooting guide and found a broken wire at the rad temp switch. Had to pull battery , battery tray , air box and move the power steering reservoir and block heater to the side..
I had to remove the FCM because the connectors wouldn’t come off and I need slack to solder a wire to the 1/2 of wire left at the connector. Dans test proved that the fans now worked in slow an fast position when jumped out .
All fuses and connectors work as advertised. Reassembled everything removed and still no fans….. hooked up my a/c pressure gauges and was only reading 30 psi on both high and low…. as soon as I added some Freon the fans came on ( car not running ).
I started car and continued to add Freon till I had 35 on low side and 180-190 on high side ( didn’t have scale to weight in Freon ) . Duct temp was 35 degrees…..sweet.
Just a note I didn’t think a low Freon charge would not allow the fans not to come on when just testing the fans out….lesson learned.
Blown lh light , replaced all’s good.
Lh brake was at the rivets and disc was missing some sections , found lower sliding pin was seized and the grease was bone dry, cleaned and regressed both pins and replaced disc and installed new brakes.
Rh side looked to be good but replaced everything with new and also repacked the sliding pins with fresh grease.
Installed helper springs on both sides for the e-brake system, the do help.
Also drivers window slow to go up to the point where it reverse and goes back down….lubed with silicone spray and slides nice now.
Adjusted hatch spring out a full turn , now hatch stays unlocked when you activate the button.
I think thats it
