Does anyone have the NAPA numbers for the heater shutoff valves? I'm without AC for awhile and in Florida it's getting pretty hot driving the last couple of days.

The part numbers are 660-1413 and 660-1414. The main thing is the size of the hoses.

Hi Terry

Eurodesk here, I have a problem with my blow fan, I think it's

a electrical problem some times the fan works and other times

it doesn't. I'll check all electrical connections and wires, do you

have any suggestion about how to test out the problem? I

want to try to fix this my self before I give up and take it to the

shop. Thanks. Marion

Check out this previous thread. It might help you narrow down the problem.

Hey Marion. Usually when the blower motor works intermittently its bad contacts in the motor. When it doesn't come on give the motor a tap and see if it starts. If so the motor may be bad.

Your A/C blower fuse might be overheating and shutting off. Try putting a 30 amp circuit breaker in the fuse slot. NAPA has them $2-$3 bucks, just ask. good luck, Gene

Anyone ever use the r12 direct replacement like Freeze 12 or something of the like??? As I was always under the impression that 134a tends to leak out of "older" systems because of the hoses... that 134 needs teflon lined hoses...?? Fact or fiction??

I would stay away from Freeze12. It is very volatile and could cause big problems in a front end collision. I tested it in a few fleet cars and it worked okay but those cars are now long gone. As far as 134a leaking out moer than r12, I personally believe that is a myth. I converted my F150 and Vette to 134a and have had no problems at all. I needed to change the high pressure hose anyway so I didn't have an old hose concern. But the rest of the system is original and as previously stated...no problems.
