My 1988 bmw 325i had the entire a/c system removed will that affect the heat on my climate control also


Hi Vince.
No this shouldn't affect the heat on your climate control, as the air-con is a separate entity the heat is transferred from the engine, but the air-con cold is a complete unit on its own so should not affect heating the car, just cooling it inside. hope that helps

98 buick century , with auto climate control ,


is it HOT or just not as cold. If its HOT, like heated air, there is a door problem, if its just not cool, the a/c refridgerent is low and will need a recharge, most likely the comp is leaking.

2000 mercury grand marquis air conditioning won't work


1st Thing,
Located Someone With a Set Of A/C Gauges 134A Freon,
Make Sure Your A/C System Has Enought Freon In It, There Is a Low Freon Pressure Switch
In The Electrical System, Usually, 50-60 PSIG or Less On The Gauges, Will Indicate Low Freon, When Freon Is Low The Compressor Is Dis-engaged To Prevent Compressor Damage.
1] Low Freon
2] Bad Low Pressure switch
3] Blowen Fuse[s]
4] Electrical Problem[s]
[a] Digital Climate Controlled ?
Climate Control Self Diagnose From Button's On Unit, OEM Manual Explains This,
If Yor Auto Has Digital Climate Control.
5] Bad Compressor DC Coil

Note: Does The Compressor Engage, Click-On When Button Is Pressed, But Getting
Only Warm Air?
Is One Of The Compressor Aluminum Tube's Cold, Be Careful Other Is Really Warm/Hot,
If Cold and or Sweating, Dripping Water [Normal], You Are Blending Hot Air w/Cold
Air At The Heater Blend Box, Making Warm Air.
If This Is So, If A Vaccum Controlled Temp Unit, Check For A Vaccum Hose Bad,
Should Be Either 1or 2 Vaccum Lines Going Into Firewall To Feed The Controller
Unit, If OK, Might Be a Bad Blend Box Diaphram, [Control's A/C air, Blocks Off
heater Coil Hot Air].
If Your Auto Is Vaccum Controlled, Can You Changed From Bottom, Dash,
Defrost Air Flow?, Yes, No Vaccum Lost Feeding Controller, Still Might Have
Bad Diaphram Blending Hot Air w/Cold If Your Have Cold Alum-Tubing In
engine Compartment.
If Digital Climate Controlled, Might have Diaphram's, Vaccum Controlled or
electrical Servo's Controlled vs Diaphram [Vaccum] Controlled.
This Might Help, Hopefully, This Is Just For Starter's, There More To Some System's
and Without The OEM Mgr's Manual[s] You/Be Would Be Lost, especially w/Electrical.
Later, God Bless

Ac problem, passenger side is cold driver's side is not.


Hello, Here is a way to ck the codes in the climate control system.
Ignition ON
Temperature selector Left Hi Right Low
Within 20 seconds, press REST and EC simultaneously for more than 5 seconds
The LED in the car flashes and the display di A
Press auto repeatedly until all DTC's are shown. Record all DTC's
Each malfunction (short circuit, open circuit, etc) has a specific DTC
The letter "E" (error) is displayed in the left of the display and the DTC is displayed in the right of the display. By pressing the AUTO button the next DTC stored in memory will be displayed
To erase, This is only possible after all DTC's are read out
Simultaneously press both AUTO buttons for more than 2 seconds
"d" will be displayed on the left side of the display window and "FF" on the right side
The only problems that I can think of that will cause this problem are as follows;
006 right heater core temp
020 right duo valve
I hop this helps. CYA Gator241
