Question Asked: Fan kicks on when I turn heater on.
March 22, 2010, 03:37 PM
I was driving my 95 Lumina APV yesterday & had thought I had the check engine light problem solved with replacing the vacuum hose to the fuel pressure regulator. I pulled the ECM fuse put it back in drove her a good 20 miles at all speeds. Before it would come on with in 2-5min. of driving her.
So I turned the heater on & the fan kicked on (i have noticed this in past so not sure if this is normal) anyway as soon as I put the heater on the CEL went on & stayed on. I turned the heater off the fan kicked off but the CEL stayed on. There was no hesitation or anything running wise. I just don't understand why the fan would kick on when I turn the heater on & more so why the CEL came on then?.
As I said a good 20 miles at all diffrent speeds & no CEL until I put the heater on!.
Question Asked: OBD1

So I looked under the hood & it says OBD1 certified. So were is the B pin so I can run a jumper wire to get the codes out?
Looking at the plug the A pin top right the B pin should be right next to it on top nothing. Under the A pin there is a pin but I don't want to jump that as I don't know what it will do.
There is a total of three pins? If it is an OBD1 I should be able to get the codes but what pins do I jump?
Question Asked: OBD1 or OBD2

I'm going to buy a code reader but when I looked for one all the ones said 1996 & latter for OBD2. My van being a 1995 I thought great OBD1 I can jump the A & B terminals to get the codes.
Having said this I went out to do this & yes my plug had 8 pins like the OBD1's closer look I saw the A pin but no B pin it was empty. Although she does not have 16pin plug & looks like an OBD1 plug it must have the OBD2.
My question is she is a 95 the plug looks like the OBD1 but no b terminal this must be an OBD2?
I just want to know so I can buy the right code reader.

As I stated earier today my check engine light comes on about 15 min. into driving her & stays on this has been going on for some time now.
What I noticed just now is the cooling fan stays on & does not shut off I checked the temp. with an infrared gun & it's runing the normal temp.
Where is the switch that causes the fan to kick on?.

My check engine light has been coming on for about 6 months now but she has been running great. It comes on after about 5-10 min. of driving her no matter what the weather is.
Having said this she has the 3.8L in her about two week ago I noticed a what feels like a miss at about 40 mph she has a miss but when I step on it she has great power no hesitation.
Today when I was stoped at a light I noticed what seemed to be a miss. As I said this light has been coming on for a good 6 months or longer with no problem.
Anyway what I would like to know is what sensors set off the check engine light?.
I know I should bring her to a garage but being out of work I was wondering if someone could just tell me what I might check?.
I collect old cars (Chevy's) no computers so I would know where to lok
