Coincidences, are just that, not proof of anything.
find the reason, first then lay blame.... or look like a (xxxxxx)
what i do first is find all paths that fuse feeds. (always)
examine the harness near clutch pedal and heater for physical damage using a flash light.
the prove what path is bad using a magical device, called and ammeter. (ask for examples)
I have the FSM book in my lap and PDF at hand.
so what do we have here, my guess is HEATER FUSE 30am blew.
"HTR" fuse.... ok,,, Chapter 9 in the real FSM.
the fuse is marked HEATER, and is fuse #26, my book shows it as the only load, (makes this 10x more easy)
it's the wire. leaving said fuse to loads.

so unplug the blower fan relay, the fuse is 30 amps. if the wrong sized fuse is used (lower) it will blow, but if a 30 blows with the relay removed?, then the LT green wires is shorted to the body.
if the fuse only blows with relay in place that means the output side of the relay is shorted and is the the RED/blue wire,
this wire goes to the blower motor. only.
if the fuse dont blow with the blower plug pulled, that means
the blower is shorted, (bad motor) (if still blows, then the wire above is shorted)
the blower switch grounds the other side of blower and thus can not be it.
if you need a schematic ask
or login at and look like all mechs do...
all that and my meter is still in the tool box.

i have a tool that does this faster.

the red thing replaces the fuse.
and the meter finds which wire is shorted. (or not)
good luck.

I would have taken it back immediatly and told them that it worked before and oesnt now since they worked on it and you would appreciate it if they at least looked at it.

If they refuse, then never go back and you will have to trace the problem using a voltemeter.

Make sure the fuse is the right Amperage.

Buy a repair manual from a auto parts saled store and see what else connects to that fuse, you could have a bad blower motor, or some other wire that got damaged durring the clutch install.

good luck

Heater on 2007 Suzuki vitara blowing warm air only

hvac 101

windows fogging up
well that takes 2 things working to do that 3 really
1: heat, you have heat. and blower works.
2: you need the dampers to work, to send a/c side air to the windshield. (it mixes heat and a/c flows)
3: the A.C must work it is the DEHUMIDIFIER PART.

i do not understand at all the sticking thing,
are you saying the controls are failing, ?

Where's the relay for the blower located in a 2001 suzuki xl-7 grand vitara

the car has 26 relays!@
and 1 to or 3 fans
are you saying the heater/ A.C blower is dead./ the HVAC?
or engine fan (its mech for rad)
or condenser fan, no symptoms posted, just relay hunts.

my guess is you dont know how the blower in the heater works.
so will cover that.
First test is blower in high, failing is bad fuse.?
if lower speeds fail, (a top clue) then the blower resistor is bad.
but only on the manual hvac option!

lets backup,I have full parts list on your car, here, USA. spec
the car came new with 2 class type of HVAC
manual AC with blower resistor
full auto system that as a new brain box, and a transistor box
that controls blower, at all times, its just a transistor. (no brains)
some cars with the full auto HVAC feature
have a self test mode.
and self calibration feature (learn) all this is in the BIG BOOK.
apples and oranges, different to the extreme.
so instead of me guessing car you bought. ill tell you to RTM

just 4 bucks, and only covers that exact year, and car only.
not a clone book as the folks post here , RAG books.
the real deal here from suzuki actual....

the BIG BOOK. see chapter HVAC and read.

The heater on our 2001 Grand Vitara 2.0 Diesel has stopped working. it only blows cold air. How can I fix this?

on my 2001 vitara the heater core was no good, replacing it was an expensive pain in the *** so i traded it in. i did however disconnect the heater hoses and blast a garden hose back and forth
through the core several times which gave some detectable heat. So i am sure that my core was bad. I have since read however that there is a common problem in that the cool air blender flap gets stuck open and that a dealer can fix this in a jiffy. before attempting a replacement i would call a dealer and drop by to make sure that your blender flap is not awry. you can buy a repair manual CD on ebay for about 10 bucks.

Hi, I have a 2007 suzuki grand vitara and recently the blower stop working now i have no air or heat. help!!

Look first for the fuse of the blower unit in the main fuse box. replace, if this blows off again the blower fan is faulty.
However if the fuse is intact then you must check the blower switch on the dash for poor contact.
replace as required.
