    Electrical High Speed Radiator Fan not coming on with AC on

    I understand and applaud the desire to keep it looking stock but this issue is a pain to figure out. It's just not worth it, IMHO. If you're willing to cut your fan plug wires, you could switch the low and high speed wires (cut, solder, re-loom). That would in essence solve the issue if I...

    Electrical High Speed Radiator Fan not coming on with AC on

    You don't need to resolve anything to use the DC Controller. It's a stand-alone system (fox III's, which had no electric fan, use them all the time). For tracking down the actual issue, it would be personalized circuit tracing. I've seen your same issue once before, and a different computer and...

    Electrical Battery light comes on and goes off

    Jozsefsz said exactly what I was going to. To check the brushes on a 3G takes only a minute, just pull them and note how short they are (compared to the 'holes' in each brush). If they're worn down near the holes, swappie time.

    1995 Mustang Cobra Radiator Fan operating only when A/C is on AND only for a few seconds!

    Your post is a little confusing. Have you bench tested the fan motor? Disco' the pigtail to the fan and apply FUSED battery power (and ground) to the low speed and then the high speed fan terminal to ensure each speed spools up and stays running? Is the ECT disconnected? The fan should not...

    95 GT- Need Help Identifying connectors and wires, please!!!!

    Knowing the location of the connectors might help. Is Sorscode still around? If not, look for his website and old posts. That dude had mapped about everything with some of the swaps he did

    Electrical Aftermarket Keyless entry

    One clue to see if the car came with factory keyless is to lock the doors and lift the driver's side exterior door handle. If the interior light comes on, that indicates factory keyless. You could get new fob(s) and program them (you undo the driver's side of the trunk liner to access the...

    Electrical High Speed Radiator Fan not coming on with AC on

    Your high-speed fan should come on with the AC, that seems to be your issue. The degree of solution depends how ambitious you are. You could try and figure out what is wonky or simply come up with a work-around. To do the former would be a real hassle, and not something most people would want to...

    94-95 Electric fan wiring

    For clarity, your fan control is tapped into CCRM Pin 17, yes? [The assumption is you installed a switch to ground on Pin 17]. Pin 17 is only for fan control, not powering the fan. As I recall, the fan's power circuit is protected with a 60 amp fuse, not 30. Have you any reason to believe...

    94-95 Electric fan wiring

    What year/trim? If your sig is accurate, you might wanna try the S197 sub-forum. If not, more info is needed.

    Any "old" stangnetters left?

    And you are who? If it weren't for an update from Paul some years ago, I'd have thought you vanished. :p BTW, the new ride looks like fun. :D

    94 Gt Running Extremely Cold

    The EFI won't lean out like that. It's a slight variation to eek temps up a smidge. This goes back to the Fox III (87-93) code. If you lean out a meaningful amount, you'll throw codes. If your 195* was operating properly, your temps should have been around 205* with the fan on or off (unless...

    94 Gt Running Extremely Cold

    No to both. I'd want to know explicitly what temps the car is seeing. The IR thermo gives an idea, but it's relative. For instance, if you went from a 180 to a 192 stat, the IR reading might have gone up 12*, but it might not be the absolute temp. We need the absolute temp now (from the ECT, a...

    94 Gt Running Extremely Cold

    That's not too bad, especially during diagnostic driving (like you've been doing).

    94 Gt Running Extremely Cold

    If you've made a rig to check ECT temps, keep it in there for further testing. See what temp it reads when you think the car should be at operating temperature. How bad is your mileage? I'm just curious (it might not be related).

    94 Gt Running Extremely Cold

    Ok, I understand now. IMHO 10 minutes to reach operating temps while in the 60's isn't super unusual, but if you're not reaching your t-stat's rated temp, something is going on. I generally don't recommend it since one could get burned, but if you remove the rad cap and let it warm up, you can...

    94 Gt Running Extremely Cold

    If it gets up to temp with the fan disconnected, can we assume it does the same with it connected? The fan will not naturally come on till over 200*F (AC off), so you should reach 200* without issue. Even if the fan is coming on earlier than stock, the mechanical t-stat you replaced should...

    94 Gt Running Extremely Cold

    I'm getting confused by the seemingly conflicting posts................ With everything connected properly, is it running too hot or too cold?

    94 Gt Running Extremely Cold

    I might have missed what stat is in there now, but to add to Richard's thoughts (which are spot-on), it could also be indicative of a performance 180* t-stat (the ones I've tested start to open at just over 170* and are fully open just shy of 180*).

    94 Gt Running Extremely Cold

    That'll work fine. Same for the top of the radiator if you have access.
