Suburban :: 1999 - When Press AC Button / Indicator Light Comes On But No Cold Air
Jun 22, 2014
Another problem just came up with my 1999 1500 suburban. When I press the AC button, the indicator light comes on, but no cold air.
I am searching for some schematics at the moment and thought I'd drop a post here for some expert advice.
I realized that the ac clutch does not engage at all when the button is pressed. Does this mean low refrigerant, bad relay or switches?
It all worked a few months ago, before I started fixing the random engine misfire problem. But I did not touch the AC components back then.
Also, read some info on using a scanner to find info on AC request. However, not sure if this scanner (MD9000) has that ability (it's a friend's).

I was playing with the settings on the Display Audio/Setup/Vehicle settings.
I turned the "Key System with Elec. Key" setting to off.
Now I cannot turn the Power on in the car. I can unlock/lock the car using the buttons on the key FOB.
But when I press the Power button with my foot on the brake, all I get is the red "no key" security indicator on the display.

I purchased a 90 Suburban and the fuel gauge reads low. I then changed the fuel pump and sending unit. The fuel gauge still reads low.
Then I noticed that all the gauges read low. Temp is low. Oil press is only a quarter up, the ammeter reads zero.

So here's the deal...my '99 Sub has developed the problem of the A/C running too cold and freezing up the evaporator.The specs call for the clutch cycle switch to shut off the compressor at 25 lbs-low side, and turn it back on at 45 lbs. With a static pressure of 120 lbs, ambient air temp of 85 degrees, engine idle 1200 RPM: when the system is turned on the compressor activates and the low side pressure stabilizes at around 30-34 lbs...the high side sits at around 180-200 lbs...fan on high, max setting on temp control, the middle-front register reads 28-36 degrees.
This is great for awhile until the evap freezes up and airflow is restricted. The lowside pressure will not drop down to 25 lbs to activate the switch to shut off the compressor. I even installed a new pressure cycle switch to no avail since the pressure will not drop enough to activate it anyway. So every half hour or so, I have to manually shut off the compressor at the control panel for about 5 minutes, and then start the process over again. The rear unit is controlled by the TXV and continues to function just fine (rear register temp 36-40 degrees).

About 2 months ago, I had the battery replaced in the key fob just because it was over 2 years old. Today my first messages I get is "key not found". Key is in my hand. Then the next message is press start button with key fob. Finally got the car started. Is this a sign of bad battery in fob or something else?

After setting the climate to 70F, Auto, and driver controlled for all occupants, start-up volume adjusted, e.t.c, I press the "STORE" button under the user profile settings. The key has been synced.
Every time i start the car up, it maintains these settings. If I press the big round knob on my name, it goes to these settings (my name, and assigned key icon)
However, if Im driving, and lets say, i adjust the temperature to 76F, then maybe later starts to get too hot, or cold, and I want to go back to my stored setting, it does not, it just stays on the new temperature. If I change the temperature manually again (2nd time), and I press the stored setting, it goes back to the setting i just had, which should NOT be stored. It usually just ignores the stored setting.
I also noticed that you can either press the large round knob, or the bottom right tap button where it says "SELECT" for your stored settings.

My roof will not open. When I press the button, it only opens the rear trunk and could hear the roof motor unlocking functioning, but will not open. It only opens about a couple to few inches and stops. It seems tho it's going to open, but gets stuck.

So I went to my garage, and wanted to go warm up the car. Didn't realize it was in gear (since i don't sit in the car but just reach for the clutch and press the start button). Apparently it was in gear and it jerked forward.
Now my DRL's don't turn on when the headlights are off. When the headlights are on the DRL's turn on but is dimmed which is normal.

I traded in my 2009 passat CC GT TDI and drove away in my spanking new phaeton full of smiles now after owning it for three weeks that has turned to a as its let me down four times and now yesterday after failing on my drive way was collected by the garage and taken back to the dealership for investigation.
The problem is when the car is cold sometimes it gets stuck in park. The symptom is the car starts fine and with the foot on the brake the green light goes on the dash and the light by the stick but im unable to press in the silver thumb button so i can select a gear. I can feel the the solenoid through the gear shift operate but the button still wont go in.
The car has only traveled lest than 1000 miles. I am really disappointed as you can imagine having saved up a lot of money to buy this luxury car. I know the garage will get it sorted but am I alone in having this problem.

I just noticed if I turn off the car without putting it in park it would do it automatically. Is that safe or do you always put it in park first?

AC stop working after an alternator replacement ?. I tried crawling under the truck to see if the mechanic didn't plug the compressor back in as he said he had to take it off to get the Alt out, but it looks like the plug is fine. Would the refrigerant have leak all out when he took it off ?. Should I try to re - charge myself with Red - tek kit from Canadian tire ?. The compressor will spin easy enough when I reach down and move it by hand but will not engage when I press in the AC buttons.

I'm wondering if my 2010 Toyota Highlander has a feature that my old Lexus and my old Infiniti had.
When you pressed and held the "unlock" button, it would first unlock the door and then it would start rolling down the windows and sunroof - an excellent feature in hot, humid Florida.
I called the Toyota dealership where I bought my Highlander and they told me 1) they didn't know, and 2) I could bring it in and they could hook in to the computer (at their hourly rate) and let me know. In other words, I can pay them to find out what their technicians should already know about the vehicle.
On my Lexus and Infinifi, it was set by a key fob button press sequence so I was hoping that 1) the feature deos exist, and 2) it's an easy and free setting change.

I have a 2007 nissan Altima and the sun roof is not working. It does not go back when you press the button. The vent will go up when you press the vent button on the sunroof but the sunroof itself will not go back. I have checked fuses and it's not that. Also it seems that the top of the sunroof on the outside of the car seems to be dropping down slightly on the left side. Could it be off track?

Sometimes (not all the time) when I get into my car with my key fob in my pocket, the car decides to let out a 2-3 second beep when I press the start button. (similar to the beep that occurs when I walk away from the car while its running and the fob is in my pocket) I have tried looking in the user manual, but I haven't found anything to explain why this is happening. Needless to say, its kind of annoying.

2011 Sonata, 42,000 miles. Every now and then the car wont start. Press the start button, everything lights up. Instead of the car then starting I hear a small clunk and then no start. I DO NOT get the "Press the Brake pedal" message. The last time this happened we tried repeatedly to start with no luck. The car then sat for a day. I tried it again with no luck. I them removed the battery clamps and cleaned the battery terminals, reinstalled, put a Start/charger on and tried it again, with the same result. I then opened the engine compartment fuse box and attempted to remove the two "start" relays. They would not come out, but I was able to jiggle them slightly. The next attempt the car started normally. Started normally again this morning.

I have a 2011 Santa Fe. I had to take it in for service in April because the shift lock was not acting correctly. Since I have gotten it back, it will not honk when I press the remote button twice. It did before the service was performed. The lights flash properly and the doors are locked, but I still want it to honk sometimes. Is there something that was turned off that I can turn back on?

I woke up to a surprise this morning , the car earlier had this kinda issue where i would press the start button and it would not start and only make "Click" sound .. and after few attempts it would usually start and then this issue went away for few months for unknown reasons
Today it returned back i didn't move the car for 2 days over the weekend down here. I tried to start the car all it would do is Click sound but this time a very faint sound not like earlier where it was much louder .
I am assuming its the starter ? Where is it located ? What i read online and see could be just a bad starter selonoid .

Recently, I have had a problem with my moon-roof, this is the second time this has happened. Normally when you press the open button, the roof slides all the way open, slides all the way closed and sealed when you close it. It also opens when you remotely open all the windows. OK, for some reason it stopped doing that! You have to press and hold the open-button to open or close it, and when you close it, it won't seal right unless you tap the button just right as it closes. When you open all the windows remotely, the moonroof remains closed.
The first time it started doing this, I took it to my friend's independent Lexus service center (now defunct) and Lee did something with the button to reprogram it and the moonroof worked as before. Recently it stopped working again. I don't know if I pressed something I shouldn't have or what! I assume that there is a way to reset/reprogram the moon-roof, just like there is a way to set the doors to lock - unlock when you shift the car into drive or park? What can I do to save an expensive Lexus dealer reset? My car is 2004, Levi/navi and loaded.

Just wondering if I should be concerned. It doesn't happen every time, but it sounds like grinding of a gear or something like that. I made a video .....

I have a 2002 Hyundai Accent. The press button inside the car no longer works so the A/C has been stuck ON for some time now. I don't live in a hot area so going without A/C wouldn't bother me too much. Is there an easy (read cheap) way to simply turn off the A/C from under the hood? My brother says he wants to remove the A/C belt but his knowledge of cars is often dicey. Might fix the problem, might blow up the car.
