I've been searching the forums for a week or two, but can't seem to figure out this little issue. I have several issues with the HVAC system (2004 LX Levinson Nav Head Unit). First issue which started 2 weeks ago: My front HVAC fan does not come on at all. Rear climate control still works...

1998 Lexus LX470 with factory radio (pre-nav) and digital readout/automatic climate control. So, about 3 weeks ago, I started my car to let it warm up as it was -10 and let it run for about 15 minutes. When I climbed in to go to work, I realized the fan wasn't blowing. I played with the fan...

The rear heater on my '93 is not blowing. If I stick my fingers in the vent I feel heat and the fuse looks fine. What do I need to do to fix this?

The blend door on my 93 is apparently stuck open. There is no heat when you turn the heater on and there is cold air that comes in thru the vents during any drive in cold weather. No water on floor, no overheating. Heater valve has been replaced, just in case and appears to be functioning. Took...

SoCal PARTS FOR 93-94, Parts for 95-97 I do not have the AC amplifier for 95 - 97. I do have systems from 1993 to 1997, R134 Compressors $85 with clutch Condensors Hoses, AC lines, etc. Dashboard Control Modules

I have had the A/C problem where a couple fan speeds work and couple don't..Then I replaced amplifier above accelerator pedal after drilling holes in it so water can drain out if need be. That fixed the problem at the time, two years ago. So I have experienced that type of problem. This is...

Yet another thread on home HVAC issues.... House built in 1999 Main R410a HVAC (outside unit) replaced in 2010 and Evap coil replace in 2012 and supposedly still under warranty Spent $600 last year on R410a to refill system in August. Turned on this year and no cold air. Told I have a leak, not...

The automatic climate control system in my 97 40th Anniversary LC can be set to full heat or full cold only ...nothing in between (like warm) ...when in automatic or manual setting. So my only adjustments are Hot, Cold and fan speed. Any explanations or suggestions ? Thanks !

Good Morning everyone, hopefully I didn't miss a thread about this in my search. I currently do not have A/C in my recently acquired 40th and would like to hopefully rectify the issue before the weather gets too warm. Symptoms are the engine idles up as I feel like it should when I push the A/C...

I want to replace my hvac controls. Some of the sliders are very hard to get moving. Also one of the plastic levers is broken. I found what I think is the correct part number. The folks at JP CarParts say it has been discontinued and the controls for a 1990-2004 model can be used. Among other...

Any ideas on why my HVAC blower would work when the weather is warm and not when it's cold? Heat and AC work fine it's just the blower. 89 HJ-60

Recently purchased an LX450. It has the automatic climate control. All of the fan control options and air location seems to work, but no matter where I set the slider it's blowing max hot air, unless I set it to the lowest setting, in which case it blows max cold air. I downloaded FSM and...

Very new to this section. 97 lx. Driving to work in the dark. The heat controls are very dark. Do I have some bulbs burnt out? How easy to replace? Part numbers? Best place to buy?

ref: '85 FJ60 A scanner was installed in the ash tray slot. I need to remove that plus see why the fresh/recirculate lever won't move full stroke. The HVAC controls, ash try and some switches are in a panel in the center of the dash. Question: Can that panel be pulled without removing the...

I'm in the process of replacing a ton of center console and dash bulbs on my lexus lx450 (1996 locked with 172k) I recently noticed that there is always air blowing through my air vents and that the air recirculation feature is not working. I have pressed the button andnthe light changes over on...

Mudders, I've had a few ask, so I think it warrants its own post - I assume more might have had/have this issue. Maybe this could end up in the FAQ, if enough people post solutions to HVAC problems (with pictures!). PROBLEM: Temperature control for HVAC does not work. Cold is cold, 65 and...

My 1997 LX450 would occasionally over the years have an issue where the HVAC (all of it - heat, ac, fan, etc) would not do anything until I pushed a few buttons on the controller and then it would work fine. Fast forward to now - I got the it back from being in the body shop (left rear quarter...

Purchased my first LC 100, 2003 model, last year around the beginning of winter here in Florida. Early mornings got cold and I might have turned the heat on twice. When I had the heat set on full blast it was blowing cool air and never got hot. I didn't think it was a big deal at the time as...
