A/C always on?..
I discovered last night that the AC clutch it ALWAYS engaged on my 92, no matter what the settings on my ECC are (including OFF)
does anyone have an Idea what might be the cause of this, and how I might go about fixing it (other then wiring up a over ride switch)
the only thing I can think of is the ECC I have in the car it a second Gen, and I DONT want to take that out to "fix" the problem, because I Really like being able to control where the air blows out.

Pull the ac relay, if the clutch disengages then you need to see if the relay is being turned on. if its not the replace check wiring then replace relay with a new one.
if the clutch doesn't disengage when you pull the replay, your clutch might be 'stuck on'.

Other relays in the Relay C enter are the same part number. Take one of them and put it in place of the AC relay. See if it works, then you'll know if it'* the relay. Quick check for defective, burned, or stuck on, relay.

Relays 101.
Relays use a small current to control the switching of a larger current via an electromagent pulling closed a set of contacts, much like the flipping of a switch.
Almost all relays are labelled the same though there are different types :normally open, normally closed... Automotive are almost always normally open
thepins on the botton ate labelled 85, 86, 87, & 30.
85 & 86 are the control current. Typically 12v is hot on pin 86 and the computer (usually) will supply ground to pin 85 to energize it.
pin 30 is power 12v in (high current) and once energized pin 87 is the high current 12v out.
The easiest way to test the relay itself is to swap in another as mentioned.
If the problem is still there then you need to check the contol line going to pin 85. It should not be grounded if the Ecc is not calling for AC. Check for a short to ground on this wire with the relay out.
