The big connectors yuo sure have to press the clip and then they should come off. You could try with a flat screwdriver on the small side of the connector to wiggle a bit, if you just get some play in it, it might be easier to pull them out. However, if I remember correctly, you don't need to...

I don't remember the partnumbers. Car is in a different country so unfotunately I cannot check. Replacing the bulbs is not an issue. Removing and installing the control panel part of the dash is less than 15 minutes. Replacing the lichts for the individual knobs need soldering. As I remember...

I have a working replacement now from an anniversary LC80 with auto climate function. However as these units are scarse, expensive and breaking down I would like to try to repair the old unit. All the traces on my board are looking ok. I tested the 5 transistors on the main board and they seem...

Not 14. If I measure the outside it is more like 19, 20 or 21

Does anyone know the size of the nut? I only have 6-point sockets. Have to buy a 12 point but do not know how to measure a 12-point

Great thread. I found a cheap replacement for the AC Automatic Amplifier (P/N 88650-60091 works) but will try to repair the original one (P/N 88650-60211) just to have a spare. It looked pristine inside, but probably one of the transistors died.

My AC Automatic Amplifier looked pristine inside (P/N 88650-60211, same as 60210 and 60212). Nevertheless it was broken. Replaced is with 88650-60091. All is fine again. Also look at: LX450 Air Inlet Servo Issue RESOLVED -...

Thanks, that really helps I think. I have not followed the traces on the board yet, but anyway I have ordered 5 transistors and I will just replace them all. I will test each of the ones removed just to check. If this is the solution it really would save a lot of money and it is an easy repair...

I studied the wiring diagram for the AC automatic amplifier. I think I am beginning to understand how it works. This computer decides to run the AC, blower, modes based on sensors and buttons pushed at the control unit sort of management layer. The rest of the amplifiers are there to do the real...

Last week replaced fan, blue Aisin clutch, shroud and belts for new. This should be ok now. Now having issues with AC, fan (LX450 automatic AC) and leaking steering pump. Always fun the old cars.

Replaced the flanges now with the newer type with the needle bearings. I just assume the bronze bushings on the original ones were just worn making the drive flange wobble and ruin the oil seal in the axle. Parts are original Toyota. Saw afterwards I could have bought the bronze bushings to...

Ok, I replaced the fusible links for new ones. I had this one as spare.No change. Removed the black AC amplifier box behind the glove box (P/N 88650-60081). Opened it, all clean, no corrosion, no burns. Sparayed contacts of the connector just to be sure. No change. Removed the AC automatic...

I replaced the fusible link, no result. Tested again all 5 fuses (10A Gauge i one of them, my mistake). On 4 fuses I get 12 volts at both sides of the fuse. On the AC fuse I get 0 volts, which could probably be explained by the missing signal from the automatic amplifier.

Thanks for your reply, yes, I tested all fuses. Do not know what the 10A gauge is, but I assume the fusible link. Measured that one too on resistance and it seems ok to me. I do not understand why they used a wire for this instead of a fuse, but I have a new one and can replace it to be sure...

I pulled the white box, 88650-60211 in my case. Opened it and all very clean, no corrosion, no burnt parts. I have no way of testing it, but should be ok. I still have the issue on my control panel, which is identical to others reporting their 'white box' is corroded. Any other suggestions I...
