marcbria Posted July 11, 2011 Report Share Posted July 11, 2011 Hi Everyone, My current problem: So the problem I'm having at the moment is getting the heater unit out of the car. From what I've read its no easy task. To make matters more complicated the unit I have has a single round fan attached directly to the heater box that protrudes into the front compartment instead of a double squirrel cage style fan mounted in the front compartment. Does any one know if its possible to remove the fan from the heater assembly before taking out the heater box. It seems like I should be able to move it into the passenger (right hand) side foot well if only that fan wasn't protruding into the front compartment. See pictures attached. Thanks in advance for your help everyone, Brian Quote Link to comment Share on other sites More sharing options...
TAR Posted July 12, 2011 Report Share Posted July 12, 2011 Welcome to the forums. It's great to see another S1 being given a second chance. Unfortunately I cant help with your questions although I'm sure someone soon will. Good luck with the restoration and you are definitely in the right place for help and advice.

77 esprit Posted July 12, 2011 Report Share Posted July 12, 2011 Brian, Can't help with the heater problem. The headlights not going up is probably the microswitch located on the drivers side at the front of the "boot" rail above the windshield washer bottle. If the switch is fouled, the lights won't go up. A simple protection device to keep owners from raising the pods while the "hood" is open. Bad things will happen. Let me know if you need more assistance. There is another member who lives kind of halfway between us in Ontario who just went through the same problem.

marcbria Posted July 13, 2011 Author Report Share Posted July 13, 2011 Hi Guys, Thanks for the feedback! I haven't had a chance to look at the lights yet but thats for pointing me in the right direction! Does any one know how to get the choke to stay engaged? I've looked all over the handle and on the stromberg carburetors and I don't see any way of getting it to stay on when I pull up on the handle.

77 esprit Posted July 14, 2011 Report Share Posted July 14, 2011 Been using a properly sized socket for years! When you find out the corrrect way to adjust it, please post the info. Thanks. Lyn Quote Link to comment Share on other sites More sharing options...
Nelly Posted July 14, 2011 Report Share Posted July 14, 2011 I have just outlined how you remove the fan and heater assembly for another member - see this thread: http://www.thelotusforums.com/forums/index.php/topic/44098-coolant-smell-with-heater-on/page__pid__368215__st__20#entry368215 I have the different fan as you mention but the principle should be the same in that the fan comes off first and then the heater assembly - which undles from the front compartment but obviously comes out in the cabin.

marcbria Posted July 14, 2011 Author Report Share Posted July 14, 2011 Lyn a properly adjusted socket? I love it, and just the type of solution I guess I'm going to be relying on = ) Thanks for the tip! If I find a better method I'll let you know. BrianHi Nelly, Thanks for your help pointing me to your other thread. My heater unit is a bit different than yours, the blower assembly is nicely screwed on in the front section, on mine it appears to be fixed directly to the heater assembly behind the fiber glass wall which separates the front section from the passenger compartment. Now that you've pointed out it may be possible to remove the matrix without removing the rest of the heater unit I may have a go at that route. Thanks for the tip!

marcbria Posted July 15, 2011 Author Report Share Posted July 15, 2011 Hi Guys, A little update on the heater assembly problem. The fan is round instead of the double blower rectangular unit and is welded directly to the heater assembly and sticks out approximatly 3 inches through the black plastic housing into the front compartment but not past the fiberglass wall. Because its attached to the heater it was really hard to get it out from within the car without taking the dash out but I managed to somehow! I contemplated taking the side of the heater unit off (as neil suggested you might be able to do in his thread http://www.thelotusforums.com/forums/index.php/topic/44098-coolant-smell-with-heater-on/page__pid__368215__st__20#entry368215 ) to get access to the matrix but I discovered that the screws that hold the side on are all around the outer edge making in impossible to get to some of them while the unit is in place. So heres what I did. - Removed every bolt/screw that was holding the plastic covers over the air intake. - Removed all the duct work and glove box (Including the vents that go through the dash) - Removed all hoses/cables connected to heater box. - Removed the bolts holding the heater unit to the fiberglass wall. - Removed the screws holding the plastic housing the fan was pocking through. - Disconnected the resistor that was in line with the wire harness to the fan and the other fan leads (I'm going to need to replace that, all the wires were melted from the heat dissipated by the resistor) - Then with everything loose slid the plastic housing and heater assembly together into the passenger foot well and with a lot of shoving and grunting out it came! (I cracked the already slightly damaged plastic housing a bit more, so that will need to be fixed) I don't know if thats the "right" way of doing it, I suspect not but its out. My plan is to cut the fan housing of the heater assembly and get some flanges welded to it so that I can bolt it onto the heater assembly from the outside of the plastic housing so that it no longer pokes through it. It wont be original but at least I will be able to get it back in. Pictures of the heater assembly to follow, I was way to tired to start documenting last night when I finally got it out a 2am!

Nelly Posted July 15, 2011 Report Share Posted July 15, 2011 Thats pretty much how I did it on m S2 but I didn't need to disconnect the fan as the wires were long enough. It is not the nicest job to do! Hope all goes well, I would suggest you get your heater matrix re-corred if you don't already plan to.

marcbria Posted July 28, 2011 Author Report Share Posted July 28, 2011 Hi Neil, I just got the radiator core rebuilt and I'm preparing to put the heater unit back together. There is a lot of sanding to do it looks like the anti-freeze dripped all over the inside of the heater box and rusted things out a bit. From what I can see there is very slight pitting of the sheet metal but it should be fine once its re-sprayed. Brian Quote Link to comment Share on other sites More sharing options...
marcbria Posted August 16, 2011 Author Report Share Posted August 16, 2011 (edited) Hi Everyone, I've finished rebuilding the heater box and re-installing it in the car. It was rotten pretty bad as you can see in the pictures so I re-cored the matrix then sanded and painted the whole box. It looks and works much better now! Its a really big job to do and no part of the removal is fun, but I got it back in there! As you can see in the pictures I have a blower with a single fan instead of the twin squirrel cage blowers that are more common from my understanding. The fan speed is controlled by a large resistor in line with one of the switch settings and by no resistor on the second speed setting. The wiring was badly melted and will be replaced with a larger gauge. You can see the resistor in the images. Brian M.
