 Posted: Sat Feb 06, 2021 6:41 pm Post subject: A/C temperature control switch |
 |
|
Taking my dash off (1989 Westfalia with factory AC) and AC switch broke pulling plug (switch fell apart). It's the switch which turns the AC on and sets temp, not the fan switch.
Found a part number (253 959 512) but none of our vendors have one or a replacement option and long since dc'd by VW. Not able to find any posts about how to go about sourcing a replacement switch. Anyone have any ideas on this or a solution?
Thanks in advance... |

I just posted two days ago about this with no response. Mine is shot too. Not available new I called all the main vendors. I just bought one used from Affordable German in Arizona. Guy gave me a great price and was really nice to talk to.
I haven't taken time to look at the switch so not sure if it's a POT or a rheostat, wouldn't imagine it would be difficult to find resistance values and try to source a newer replacement. |

| Thanks Remraf, kind of what I was afraid of. I'll contact that wreckers and see if they have another. I'll also look again to see if I can fix mine but it seemed pretty wrecked. I'm surprised there's no obvious alternate option... |

Drove my van yesterday. 90 camper air. The thermostat switch turns the AC off at the end of its sweep. To be honest I don’t feel a notch or click. The blower switch has positive clicks, but does not turn the AC off.

Honestly, if I still had my 86 that uses this switch I would snag one of these and squirrel it away for it seems like when these are gone, they will have then slipped into unobtanium world.

nice add-on to GW order...for my 83 I needed this same COMBINATION fan/temp switch in 2013? and thought myself lucky when a local AC shop just HAPPENED to have one is a box of random stuff.

That switch looks suspiciously like something you'd find in one if not all three of the Merkin car brands from the '60s - '80s.

| The switch in that link is for older vans, not the later style switch OP is looking for. |

| I'm not sure, but it would be nice to locate some sort of replacement. I'm going used right now so I can keep moving forward with ALL the other issues I have. But given how much time and $ I just spent converting entire system to r134 I'd love to eliminate a cheap plastic switch as a potential point of failure. |

I'm really surprised someone hasn't found something which replaces this switch. I'm looking for a used one but, honestly, it looks pretty simple. Hate to think the end of my AC system could come down to what looks like a $10 switch. |

Think it's a POT as it has more than 2 terminals I think. That's the thing, this is one of those things I just want to buy!  |

| Hmmm...good pickup, looks like a pretty simple switch. I'll have to think about that, looks like a potential solution. Thanks! |

| I'll try and take a pic of switch next time I'm with van. As far as knob goes I wouldn't worry too much as it could easily be 3D printed. I was already contemplating this depending on whether I found a decent used one. |
