My heater blower motor is not working. I need to replaced it and have looked in parts manual and the Jensen Healey shop manual and found no information on the steps to remove it.  Need help!   it is a 1974 jensen-Healey Roadster Conv.  Thanks Jim

Hey Jim,

I'll follow up the site comment here for everyone else's info.

To get to the heater on an assembled car you have to pull the dash, pull the bit between the dash & center console where the radio sits. You may have to remove the center console as well.

From there, it's the support plate in front of the heater, the heater and finally the blower motor.

I'd avoid it if at all possible until I had something more serious to fix in there. :)

I did it this winter, and like Jody says, most of the interior is built around that part. I already had the engine out, so I didn't have to waste any time on disconnecting the heater from it, and I made in in two nights, one to gain access and the other to get everything back together. Since it was the first time I had the dash out,it took three attempts to get every back together right.

Make darn sure that the fan you put in works!

oh, and Stupid Jody Trick #348: When removing the heater hose connections, use your shop vac to suck all the water/coolant from the heater radiator.

That way you don't accidentally dump it in the interior when removing the unit.

If there is a source, it'd likely be Delta Motorsports followed by Martin Robey. (U.S. then UK).

I shouldn't think they're likely to pinhole or crack. If yours fails a pressure test try your local radiator shop. They should be able to repair it for you.

Thanks,
No Joy at Delta, UK not geographically desirable so It's off to a radiator shop.
We just saw the Jensen video...my side hurts from laughing
